Newbie Needs Help with Acme Safe with Yale Dial Combo Lock - Resto Project

[Eskay]

Thanks, Tim, for your kind reply and the blueprint The dimensions from the print the of my safe. I have been continuing to research my safe and am pretty sure it is a Herring-Hall-Marvin 1898. I found an ad for one and it is identical in every way, including dimensions, internal compartment configuration, casters. However I notice that several of the different makes are nearly identical, so it could be a Syracuse. I will look for photos and conduct some further comparisons.

I have determined that the missing parts are a three wheel pack assembly for the Yale OB lock. The lock housing actually has OBS cast into it and I can not find any reference to that designation. I have the dial, threaded spindle, and the fly wheel - but no brass key. - And, one inconsistency I observe is that there is no key way on the fly to accept the brass key (see photos). A locksmith in town who is trying to find parts for me speculates that this version may just be a friction fit. Doesn't seem right. Can anyone comment on this?

Thanks again for any help.
