Hi Richard, You cleared things up for me. Thanks. Raid I wonder about that repair man. According to Prochnow _Rollei Report 2_ the serial number is correct. He identifies the camera as a 3.5F second model. The serial numbers run from F- 2,300,000 through F- 2,241,499 These cameras were supplied with either a Zeiss Planar or Schneider Xenotar with Heidosmat finder lens made by the same company that made the taking lens. Prochnow does not indicate that different serial number sequences were used for the different taking lenses. There appear to have been three versions of the 3.5F, my German is very limited so I can't determine from the text what the differences are. The Rollei film transport mechanism is pretty rugged, mostly they just get sticky from old lubricant. They _can_ be broken and sometimes parts wear out due to very heavy use. I wonder what happened to yours. -- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list --- Rollei List - Post to rollei_list@xxxxxxxxxxxxx - Subscribe at rollei_list-request@xxxxxxxxxxxxx with 'subscribe' in the subject field OR by logging into www.freelists.org - Unsubscribe at rollei_list-request@xxxxxxxxxxxxx with 'unsubscribe' in the subject field OR by logging into www.freelists.org - Online, searchable archives are available at //www.freelists.org/archives/rollei_list
