Not Germany, but I highly recommend Mike Spencer at http://www.camerarepairs-r-us.co.uk/. he has CLA'd both my OM1n and OM2, changed the foams and converted the OM1n to take SR44 cells. He sorted a dry joint in the meter circuit on my OM1 and he also changed the prism on my OM2.I have 2 OM-1ns and one need a definite CLA. I am looking for an authorized service person in Germany. Can anybody help?
