Hi - I am trying to identify a bike. Chainwheel and front lamp bracket seem to point to an Elswick but the frame has a sloping top tube, sloping from the seat downwards to the front. I cannot find an Elswick like that anywhere although there is one very like it with a straight top tube. I'm guessing it could be 20s but not sure. It has 26 in wheels, rod brakes. One strange thing is that the right brake lever operated the rear brake. Did some vintage English bikes have that configuration of brake levers and if so when did this change to the 'normal' UK set up? I would post some photos but don't think I'm allowed to yet.
Many thanks,
Phil
