ID this Vintage Mosler lock...

[MtnMann]

First successful manipulation for me. This is on a safe inside a Mosler insulated record container (c. 1950's)
I haven't seen pics of this style out there with the integrated latch/fence.
There are no model markings on it.
Anyone know more about these?

looks like a B101-F. just happens to be the lock inside a Mosler file cabinet fire safe with receding door (butterfly key locking handle) that i am currently bidding on at an on-line auction site.
other similar Mosler locks are : KCB-107, S-201, KCB-104, KCB-401.
the B-101 was used in 1940s-50s in round doors, vault doors, and fire safes.

Thanks for the info. I'm actually selling my cabinet on ebay right now... too bad we're not closer

Sorry, I'm not much help on identifying it.
But congrats on a successful opening!
Felt pretty damn good I'm sure?!

Yeah, then I had to go buy another safe to try again...
So I got this with two locks. It was locked and no combination.

It took about three hours. The bottom lock ended up being the same
I gotta quit buying safes!
