Love the Philatector! Anyone know what principle it claimed to exploit to effortlessly detect watermarks?
Hi Cjd,
AFAIK the box contains revolving discs of colours that when
given their correct matrix, highlights the wmk.
They were still for sale in Australia up until the 1980's
albeit a cheaper plastic box.
I collect Travancore as a passion, and watermark detection is a right pain in the glutinous, I have yet to find a good wmk detector
and was advised against the super expensive SG model.
I am still looking.
David Giles is welcome to that mag, it is severely damaged by previous owners ripping out bits, and it is not Canada centric, rather an eclectic group of post stories from around the world.
He would need to be quick, before it goes in the attic for storage.
