HI Basically I need both all 4 cylinders have been sitting in a pot for the last 10 years and the rubbers are breaking up. I think I have sourced the 19mm seals but i am not having much luck with the 16's. I really want to try and keep the old cylinders if poss but otherwise I would be interested in the cylinder that you have thanks. The car is June 1950 so it 16mm at the rear and 19mm at the front
