Of the three unlisted types of multiple crown watermarked papers that appeared from around 1964 onwards previously discussed, I found that the fluorescent fibre contaminated ones to be of the greatest importance and interest ! It was stated by the late Aubrey Walker. whilst working at the Dollis Hil...

Hi Jim, I think you will find an updated version of Austin Barnes original article on this site under downloads available to all members, it may be that you have already discovered it since your original posting being made in 2017, but if that is not the case, that's where you'll find it, hoping thi...

I was fortunate enough a couple of years ago in obtaining a calculator that gave you what the £ was worth in the past in comparison to it's worth today and as a stamp collector of many British periods, I thought it would be nice to know just how much people had paid for a particular stamp or set of ...

Good evening MOZ, Most of your queries can be answered by looking at the article produced by professor Austin J Barnes in an article by the name of " British post office phosphors ", that can be located by first going to the home page then go into 'downloads' where you will find philatelic...

Hi MOZ, It's quite possible that the editor of the handbook Hanns Fasching might be able to give you some information that you are seeking, I can't guarantee that you will get an answer as he is rather a busy person, but being Machins I'm sure he will try and help you rather than search for previous...

It would appear MOZ that you have a much greater knowledge on the subject than I. Perhaps you could let me know the outcome once you have investigated further. Thank you, WM.

Hi MOZ,
The vertical pair are gum arabic, but the block of 4 are PVA, I am not a specialist in the Machin issues and do not possess a Deegam handbook, please bear that in mind. Thank you WM.

Hi MOZ, I am in full agreement over the similarity of papers used for the un-watermarked Wildings and the pre-decimal Machins, however, that is not the topic ! But to compare similarities/differences between the same issue for my posting on the subject of coated papers. IMG_20200519_124809.jpg Here ...

Hi Mike, On the topic of coated papers I have examined several values other than stamps for cooks book, and noticed certain other values appertaining to this anomaly the like of which can be seen in the following scan. IMG_20210719_013157.jpg The 2d+9d values appear to be non-coated whilst the 8d du...

In the opening segment of this posting, I gave a general guide as to the three unlisted types of paper to be found issued since 1962, beginning with the problem of the contaminated papers that seem to have originated around 1964 leading to further action being taken to rectify the situation, over th...

By the way David, would you say that the adjoining cover is a long perf stamp ? If not, then could you show me an example of one that is, in order for me and other collectors to identify for future reference, as there is no information whatsoever in the the GB specialised vol l on these varieties, d...

As stated in my initial posting David, it was only to make others aware of their existence that seems to have previously been ignored by the Stanley Gibbons specialised catalogue, although your information, would be more suitable for anyone taking up this line of research on a specialised basis, in ...

Good evening David, Many thanks for your ' in depth ' contribution on the topic of short and long perf stamps, from what you say, I can see that you are well read on the subject of line engraved early Victorian stamps of Great Britain, I am not a specialist on this particular topic, as my pet subjec...

Whilst looking through the Stanley Gibbons Queen Victoria specialised catalogue volume 1, I could not but notice the lack of information relating to the almost 'Square' stamps that can be found with the 1854 penny red, unlike the normal versions with 16 perforations horizontal and 19 perforations ve...

A fellow collector by the name of Chazz Broadhurst brought up the topic regarding all of the 4d,5d and 6d values, ranging from the original 1937 dark to the 1950 colour changes as to variations found on the Thistle head in the top right of the stamps with distinct differences that he posted on the &...

Good afternoon Panned 2307 (Andrew), Unfortunately I am unable to help you with regards to the coils mentioned, but as like yourself, I've become interested in the multiple crown Wilding definitives first issued in 1959, especially the papers used to print them that can be found on this topic by the...

Good morning Busselton + Tony, The study of papers on the multiple crown Wildings is currently part of my interests, and has been for the last couple of years, the one philatelic tool that I have found to be indispensable is the long wave ultraviolet lamp on a wavelength of 365 nanometres, not only ...

The design of the multiple crown watermark is such that even reversed it would still look the same, therefore it has previously been unnoticed and overlooked in the past, and only by studying the embodiment of the paper can this be determined. Having gone through 1000s of this particular issue, I ha...

Whilst checking various used multiple crown Wilding definitives, I came across the following oddity relating to the construction within the embodiment of some of the papers used. Some of the stamps affected appear to have reversed lines in them, as if the paper roll had been reversed during the wate...

My search in respect to the manufacture of stamp paper lead me to the Stowford paper mill sited in the small town of Ivybridge in South Devon, that was used by the GPO for all their stamp products and supplied the paper for the printers Harrison and Sons for all their Wilding low values produced, th...

Dear GbB,etc, It would appear that your query posted back in 2018 has not been responded to before now even though you have had over 15000 views, which surprises me ! To identify the different types of phosphor bands applied to the multiple crown watermarked Wildings, you will need to radiate them w...

Mr Frank Walton, I have a query with regards to your scan that you submitted on the so called 3d multiple crown wildings. The cylinder 41 could only be on a cream paper (plain). Cylinders 78,79 and 81 would be whiter papers used for the printing of the 3d plain & violet phosphor centre band stam...

For all those of you that have not been initiated into the study of stamp papers you could be missing out ! Varieties are not only found in printing errors, perforations or the colour and width of phosphor bands but also in the type of paper used to print them, afterall, without the paper there woul...

ADDITIONAL INFORMATION ON THE 10d PHOSPHORS. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ From my findings, the 10d phosphors appear to have been printed on three different types of paper and are quite distinct when applied to longwave ultraviolet radiation on comparing like with like. IMG_20221103_220639.jp...

Many thanks Frank for your contribution of the variations that you have found including cylinder numbers, but none of which appear to be as highly fluorescent as the 10d ones in the following scan. IMG_20210501_100516.jpg Surely Frank, with such a vast difference, these variations can't be ignored a...

Here is another example of the contaminated papers, but this time depicting the 9½mm violet phosphors of the 6d value that gives a much clearer portrayal of the anomaly that had to be contended with by the chemists at the paper mill. IMG_20210312_104752.jpg Along with two variations of paper depicti...

It would appear that not only are there variations in the papers that have been depicted in the Stanley Gibbons specialised part 3 as specified by the GPO in their declaration of 1962 in a changeover from cream to whiter papers, but several other variants of paper has also been used to print later i...
