Can you identify this? I think it is firearms related

I think its a wrench to tighten the barrel nut on dan wesson revolvers, the barrel screws into the frame and the barrel cover then goes over the barrel and a the nut tightens the cover as the barrels are threaded on both ends.

Thank you!
I had it for many years and I was always curious.
