I have none of these stamps yet myself.
The colour dots on the second strip have the black dot lower than on the first strip. Does ths feature create any colour shifts on the stamps themselves?
Does it also copy onto the booklet form of these stamps?
Does the slightly lower 'C' and black dot imdicate a back-printing of the Canada under ptinting?
Quote:
If the number of intervening stamps is always an even number (it seems to be 10) then the top stamp should be constant too.
I am not sure myself again, sorry, but the Adminware web site -
http://www.adminware.ca/stamps.htm - does have a .pdf (5.9 MB) document available for download than catalogues the Lowe Martin printer's coil stamps and their Serpentine perforation varieties, and your question may be addressed there.
