Joe Cooke Imperial Petrel Super Rigid?

Has a curved tube between top tube and down tube .

Also has a curved bridge between the chainstays and the seatstays .

Have a look at the "Classic Lightweights" Website for a picture.

At the National Cycle Museum we have a bike intended for the Track, behind the Motors, with an undersized front wheel and a vertical tube let in about 6 inches behind the headtube . Can't remember the make if that one and it is quite possibly a one off.
