Visited the Coventry Transport Museum here in the UK today, quite a nice selection of bikes from different ages.
Here's a few of my favourites :-
Caminargent from 1938. Spookily someone mentioned this bike in the hexagonal tubing thread. Hexagonal aluminuim tubes bolted into rather fetching lugs.
BSA from 1908. A.E.Willis used this to break the hour record, covering 61 miles 972 yards ! I presume he was paced, the placard next to the bike didn't say. Humoungus chain wheel.

and lastly what thread is complete without a Hetchins
