Help needed Razor I.D.

Hi guys and thanks for looking, i have a real old beat up Razor that I am starting to restore, Nothing new there..lol however The tang is so pitted that now I have removed the crusty red rust I cannot make out the makers name.
The writing that has remained is very clear, its my ignorance that stops me from filling the blanks.
Also I would be very grateful is someone could tell me what the scales are made of? they are almost like a laminated paper? soft enough to easily bend and they are badly warped, I do not intend to use them I just would like to know a little more about them, I think i have another blade with the same sort of scales.
So heres a couple of pictures, and thanks again for any help you can give.
