Not sure what to call this one
Bike is Claud Butler, serial number 731687.
Sturmer Archer 3 speed gear with code AM47 on hub, thus 1947 model. The patent number is 498620 (or possibly 498520).
The front bracket carries the inscription Hiduminium, which I understand (from good ol' internet) is an aluminium alloy, but also the trade name used by Reynolds for their brakes.
