The Chubb Archive, www.chubbarchive.co.uk, website is now resourced and maintained by The History of Locks Museum. We have built on Peter Gunns' original concept and also given it a facelift including the creation of on-line examples from the registers. We can in most cases advise the day/month/year of manufacture from the serial number marked on your lock. More details on the Chubb Archive web site.
