You could try: http://www.newtonellis.co.uk/ David Morgan, from Club Rollei User, has used them recently and been impressed. John This is not part of a Rolleicord. I have a pre 1936 Voightlander Brilliant that contains a 75mm f4.5 Skopar in a Rim-Set Compur. Therefore the lens is front-cell focus. The lens certainly needs a clean & the shutter needs a serious looking at. It seems to fire only at a very fast speed irrespective of the movement of the speed ring. I realise the camera is not worth much, only a portion of what a CLA might cost, never mind whatever issues a Rim-Set Compur might have after such a long time. Has anyone any ideas of anyone in the UK before I remove the lens & send it to SK Grimes in the US? BTW: As you may know my Brilliant was also made in Braunschweig.
