Paul Prescott I found this image on an old backup disc from a previous PC. I have no idea where I got it from. If it is your copyright please contact me. – I would be interested in finding an example of this lock for my collection.
Richard Phillips I’ve never seen one in half a century of looking at locks. Chubb and Gibbons also made a lever cylinder latch early 20C to compete with Yale pintumbler latches. I’ve only seen a few of the Cubb ones. The Chubb one was later copied post WW2 as the Wellington cylinder latch. Almost all production went to Greater London overspill housing.
