I just got my Zeiss Iktona IV and my Roleiflex Automat 4 back from Essex Camera Service. They did a great job on both cameras. The Zeiss Iktona IV was unused for a long while. The shutter wouldn't cock and the focusing knob was stiff. When I got it back it was cleaned up and serviced well. My Rolleiflex had a film advance problem and it was fixed and cleaned up too. I think they fixed both for a fair price. I think these old cameras are classic antique cars worth fixing if you can afford it.
