Hello stevenkuk, I'm unable to add much from memory and as you've researched them you will already know that with the exception of the Chubb (pic #2), the Stratford Sterling and the Ratner, which are decent burglary resistive cash safes, all the others are large fire resistant safes intended for fire protection of paper documents. They were often called 'record protection cabinets' back in the day, the term 'cabinet' being the hint as to their focus of importance of fire protection over security.

You will probably find you'll get more interest in the cash safes than the others, but often any value takes a big hit against the cost/work involved in moving them, unless of course your business specialises in heavy lifting/moving equipment!

The Chubb in pic 2 with the distinctive hinges, from memory they made a few varying models of that appearance, from a lower range Commerce to a pretty heavy build anti-blowpipe (ABP). The latter had similar hinges but were even thicker IIRC, but without numbers and unable to see door/body thickness difficult to tell.

Stratford made several versions of the Sterling, four in total IIRC, if the serial number you've posted is correct its probably a later Mk4 version. Might have a Sterling brochure, plus similar Chubb for idea of weights, and possibly the Chatwood Milner, but unfortunately be a while before I can look for them.
