I forgot about this one until today. I don't even keep this one with the others on the Island of Misfit Tools. This one goes with all my treasures in a locked cabinet. Picked it up a little while ago while looking for something else..
At a quick glance, it sort of looks like a factory dwarfie double offset combination box end and flare nut wrench.
That's because the mod is well done on the top side - and because it has that instantly recognizable NOS yellow US Army Ordnance Dept re-pack (long-term storage) label and tape strip wrapped so nicely around the shank.
Upon further inspection of the flip side, though, it becomes evident that someone not only cut an opening into the larger box end, but they ground down the ring underneath, except for two little areas they shaped into "pins" - turning it into a
pin spanner! (Or perhaps some kind of strange valve lapper?!)
Then, upon further inspection of the label, you realize in some horror and dismay that it used to be a NOS
41-W-625 (5/8" x 3/4") dwarfie double offset double box end GMTK spec wrench!
The real question becomes - did someone actually convert the one end into a combination box end/flare nut/pin spanner
after it was re-packed, without even bothering to take the re-pack label off?!
Or, did someone modify it
before it was re-packed, erroneously, as a 41-W-625
despite the modified end!?
I'm not sure which one is harder to believe!
