I´ve recently adquied a not working Rolleifex 2.8E. after dismounting it I´ve came across that some parts of the shutter are missing. I´ve been said that Kodak Retina compur and Rolleiflex F3.5 share lot of parts so I would like to know if there are other Compur cameras MXV ones that shares the same parts as the 2.8E in order to transplant that missin parts and get my Rollei back to life.
