I am wondering if it is celluloid with browning due to the nitrate content and age. I am anxious to hear from others. I have a very early French pocket rule,...
Peter, This is very strange indeed: it was manufactured as brown given that allthe lettering is white. Moreover, the brown is very even, which you wouldn't ...
Hi, Peter... That is very odd, indeed. The closest thing to it that I've ever seen is certain Simplon models. I have about six examples of these things, ...
To my inexperienced eye, this rule looks like it was made for student instruction, probably using some bakelite-like resin that might have been available in...
