now heres one to test the bbs experts,its turned up in a box of odds and ends
brand new and has us all at the little shop on the south coast a bit non plussed. its dims are 113 mm overall / 24.2 diam the slot is 77mm,internal bore of 21mm and the piston washer thread is m5. any ideas its relative short length but metric piston washer thread is a little differant it has no id marks.
