Did Chatwood make their own combination locks?

Gary Stephenson

Or get other companies like kromer to supply them?
Had to open one on a Chatwood Treasury today and when I look at something like a SAM lock, it makes me think it could have been Chatwood made, this one I suspect was bought in.

Huw Eastwood

Can we see some more of the lock Gary?

Gary Stephenson

Yes Huw

Huw Eastwood

Cheers Gary that’s impressive, used to see a few small ones with those hinges and dual locking always key/comb but they were never anywhere near Treasury quality like that.

It doesn’t look Kromer to me. The base design is an S&G lock which seems to have been copied a lot. The only Kromer which would fit is the 15B which has clear differences in the details of the case.

Huw Eastwood

I’m sure Tom G will know.

Gary Stephenson

The only reason I mentioned Kromer is because of Chatwoods use of some of their keylocks, so there was obviously a supplier type relationship there with them at one time. Nettlefolds and Aubin also spring to mind.

Would that triple locking be standard or is it a special order? I hadn’t seen one before. I know Ratner used to make triple lock heavy units.

Gary Stephenson

I think it may be standard on the treasury models, all three locks block the boltwork, but the kc lock also throws shutters to block the keyholes

Chubby

I suppose that is why the bolt throwing handle is so low. I could imagine that being a bit awkward.

I assume those locks are original…. Chatwood clearly kept at the very least an interested eye on American safes and locks. He copied the ideas of night deposit safes, round doors on a cylindrical safes and had flat steel keys on some safety deposit locks. I think be bought in those sd locks from S&G, so I would say he was happy to buy in product where he temporarily didn’t have the manufacturing capacity himself.

Gary,sorry to take so long to reply.

Between 1932-33 Chatwood designed and produced two entirely new combination locks.
These were Chatwood ‘A’ type and Chatwood ‘C’ type. The former had a numbered dial and as Cepassacus states was in effect a version of the Sargent & Greenleaf heavy lock finished in dull satin chrome/nickel. This fits exactly with your illustration as regards the markings.
The type ‘C’ was an updated S.A.M. 3 wheel lock with 4 wheels and alphabetical dial,

Unusual, methinks, to find any of these Type ‘C’ Dials/locks
