Chubb Serial Number Dates
The History of Locks Museum Archive contains an index to the Chubb lock serial numbers. The index lists the year, month and day of manufacture (or completion) of Chubb locks from 1819 when production started to December 31st 1936 when the serial numbering of locks was discontinued.
We are happy to look up the date of your lock in exchange for the following details from your lock:-
- Post here good clear pictures of the exterior of your lock on a white plain background, which should also include a picture of the logo, marking and serial number, and one of the lock interior (except padlocks and other sealed units). Please ensure your picture is of the complete lock and is not croped.
- Include in your post the exact dimensions (width x height x depth) and its weight.
- Any known provenance, where it was found, what it was used for etc. etc.
The HoL Museum Team will look up the index and post the date; AL members can then 'explore' your lock and its features. As well as this thread evolving into a useful resource for all Chubb enthusiasts some pictures may also appear on the Chubb Archive website.
Chubb Detector Lock 830550
Hi Sharon
Yes I think you are right with that number which dates it to 7th November1879.
Do members have any theories on the miniature stamp on the right hand flange (Prince of Wales feathers)?
Cast iron safe - lock number 8217
Hi Pierre and welcome.
Assuming your safe is cast iron, that plate would relate to the lock serial number (rather than a safe serial number) and therefore its date from the registers is 24th Oct 1836.
A nice early example, I'm sure members Huw and Safeman can tell us more about these early cast iron examples. Do tell us the safe dimensions and if you have pictures of the lock inner's we can see which version of the patent it is. The letters 'A' and 'D' on these early lock plates might be significant.
