Looking for a cover using the Boston Machine cancel #4 used in Liverpool with the 4 digit year. Only one I am missing from my exhibit.

I can be contacted at mather@eastlink.ca

Looking for exhibition 2d imperf on cover with London Maltese Cross, can email me scan and cost if you have one.
Also looking for coloured Maltese crosses on or off cover.

Thanks, Mike

Hi, can anyone direct me to a source where I can get the earliest and latest known use for cancels used during the Victorian period? Thanks in advance.

Mike
