Two cockney criminals (Tommy Godfrey and George Sweeney) break into an office to break into the safe, but this isn't a blag from the Sweeney, this is a promotional film from the General Post Office for it's fancy new Number 23 teleprinter! George becomes obsessed with the machine while his old man works on the safe and helpfully reads out from the manual all of the swish new features. This is great fun, how a promotional film should be done. I certainly want to buy a 23 after seeing this, though i guess eBay will be required these days...
