Tom Gordon wroteWho doesn’t have a soft spot for Chatwood?
Tom, I didn’t know that Chatwood’s had any soft spots.
In fact I believe that the Company created the most significant improvements to the strength of safes in the Victorian times if not ever, and many of which are being ignored by some of the sheet metal safes manufactured in current times.
The first was the ‘T’ frame (orange) into which the door fastened, and the second was the ‘T’ solid flange lockcase.(yellow)


The Cornhill Robbery of 1865 demonstrated the weakness of what were until then believed to be the strongest available. The safe, a Milner Holdfast was not opened by the above technique but by the last one.
Samuel Chatwood took the opportunity of writing to the newspapers of the time explaining that the method used would have been totally useless against his new security principals.
Please excuse me Tom for having taken this opportunity to get my admiration for Samuel Chatwood off my chest
