I posted these up on the old site about a year or so back but never figured out what they are for. Any ideas?

Could be a ring spreader for larger snap rings.

They don't appear in the 1968 catalogue...

Looks like it "could be" a small brake line tubing bender, minus the bending wheel. Or, a linkage bending tool. It seems you are not the only one looking for this "Utica B 5113" tool, as I found in my searches. I did not see it in the 1960 Utica Catalog either.

Couldn't fine it in Utica Catalog No. 66 (1957).

wvtools has a set listed on ebay, but he doesn't know what they are either...lol

Tire benders for Leprechaun buggies?

I once read that 'B' Part numbers were for tools made for vendors as special tools, so probably not going to be in the catalog.

It sure looks like a wire bending tool, or s spring bending tool, but who knows....

There sure seem to be a lot of them around tho....

Thanks for the responses. The thought has crossed my mind they may be some kind of a ring compressor kind of like the band type compressors that use hook end pliers for piston rings. But since the working end has unequal length jaws that would offset the attack angle which would imply some type of restricted access. Plus those ring compressor pliers are longer than these.

J.A.F.E. Do you think it might some kind of specialized aircraft tool. I'd guess a tubing bender but I don't see anywhere to hold the tubing.

I have considered a tubing bender and didn't see anything for the tubing either. The oddest part to me and perhaps a clue is the jaw joint seems to made the same as the discs on the end of the jaws. I can't imagine it was done that way for no reason.

I got it in Long Beach at a swap meet and Long Beach was a hub of aircraft manufacturing for many decades. They're all gone now but there are still lot's of tools they liquidated on the way out. So it definitely could be aerospace related. With my luck it will be something heavily classified and some guys in black suits in unmarked black SUV's will come knocking at my door at 3am now that I've posted it to the world.
