Old Military Socket Found, Double 12-Point Design..Any Info About this?

[MysteriousGT]

I Found this site off of a Forum Post of Another Post and i thought you Guys would Know About the History of this!

Markings on the Side Are:

K-2541841- 1 3/8
FSN-F5120-227-6693-SDGA
WRO-A4D-2-56-119

This is a First for Me to see that Much Stampings on a Socket Before...I Did a Search on Google for "K-2541841 Socket" and it Brought up a Army Property Site with a Get a Quote Button

Its a Cool Looking Socket for Sure...Any Ideas of Maker or Age?

Thanks

It is still in the Gov's database, it's new number is "5120-00-227-6693", the fact it was missing the -00- means it is old enough to predate the last revision where they added more digts (but it's post war, as it says 'FSN')

The database says an exception was made for it to have some non standard configuration for a special purpose, but does not say what it fits. I can' find anything that seems to need it...could be something classified tho ....(There is tons of stuff that's classified just because noone cared enough to unclassify it)

I own a similar socket that fits two sizes of oil pressure senders - purchased while on vacation* to change out the oil pressure sender on our 1973 Volvo after it started spewing oil all over the place (and, since Volvo cleverly put the sender right next to the exhaust manifold...well, let's just say that the smoke made it easy to notice the problem).  You generally need a deepish socket for senders to accommodate the electrical connection on the sender.  This looks very similar in intent.  Maybe this one fits the oil pressure senders on two models of Abrams tank or something.

But I'm just speculating here about this specific tool.

*Our sons sure got plenty of opportunities to observe their parents doing actual work; but the gravel at our campsite did NOT make a comfortable working surface as I changed out that sender.

The style, form and crude broaching say this could be a Thorsen product.
