    Default 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.

    Default Chubb lock 830550

    Hi, wondering if you could tell me what this lock might of been used for. The brass plate measure 66mm by 55mm, I think the number reads 830550... key works smoothly, it is more brass colored than my pictures show
    Also would you know where I can find out a value, can’t find much on Australian eBay completed.
    Regards Sharon

    Default 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)?

    Default Chubb Lock 8217

    I am in the possession of the safe in attached picture together with 2 original keys. Inside of the door shows info about the safe and/or lock. I have it from my grandfather who died 1969. I do not believe he bought it new.

    Could you provide me with more info ?

    Thanks for your help/support.

    Pierre

    Default 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.

    Thanks Brian for this interesting info and letting me join the forum.
    I'll post some dimensions and new pictures asap.

    Kind regards,

    some of the others on the display board are cheats, with just spring loaded bolts and no levers or detectors, naughty Chubb engineers.

    Default Chubb 3 lever detector 1371314

    Looking for any more info or exact dating on this please. Assume about 1900 date and that it is only a 3 lever so it can be easily keyed alike to other products on the display board it cam from.
