Perforation type on Machin se-tenant pane USB9
Posted: Wed Jun 11, 2014 11:30 pm
Hello All,
I am looking for information on the booklet pane shown here.
It is listed by Mike Holt in his price list number 25 as USB9 with perforation PAP1a.
I have a rather old (6th Edition – July 1991) G.B. Volume 4 specialised catalogue
but can find no reference to this perforation type.
As can be seen from the scan there is a break about the size of two perforation holes in the left hand selvedge opposite the central row of perforations.
Does anyone have a more recent edition in which they could check if it is listed now and if so under what perforation type?
Any help appreciated.
Regards.
Ron.
