We'll start with the rolling, measuring device. Actually not even sure if it's that old, but it was in a box full of other antiques, so I thought I might as well see if anyone knows what it is. You put it on a surface and as you move it, the needle moves telling you the distance. Strange denominations though.
Next is a drafting kit, that I THINK was either used by my father in Vietnam who was a helicopter pilot. Or by my Grandfather who was in WWII and was in the Corps of Engineers.
They are all marked with F.A.P and have a strange looking peace sign on them.
Lastly we have a Swedish Straight Razor made by C.V HELIESTRAND and on one side it says MK no.8
I have found a few things about the company and other razors, but not about this model.
Thanks again everyone for the help. I think I only have 1 more thread to post after this.
