I picked these up recently. At first I thought they were line wrenches of sorts but they are also torque wrenches. Numbers 10,11,16. I haven't measured for their sizes. The end of one has a large screw I think would adjust the tension. Other 2 have glue or something in the end I haven't dug out.
Picked this up today thinking it could be plomb due to the font style but the number doesn't seem to match. No name markings that I can see yet. Found a few newer Indestro super that matched the same number (2785) on ebay.
Believe this is cadmium covered, would it be WWII era? I didn't see much...
The closeup of the front sideways, looks like the upper half was taken from something else or reprinted. The lower portion of that sticker is more orange than red. Unlike whats in post #5.
