Rolleiflex 3.5F Model 3 Planar (Model K4F1)
Serial number dates it to October/November, 1965.
The camera is partially functional (as evidenced by the test photos) but will need a CLA. The shutter won't fire below 1/30th, and it can lock up when advancing the film. I was able to jiggle the winding lever a bit and would wind it backward, which resulted in resetting the shutter. I would then place my hand over the Taking lens to prevent a double exposure. The camera would advance normally to the next shot.
The test photos were taken with Kodak Tri-X 400, and I used only the camera's meter to set the shutter speed and f-stop. Shutter speeds above 1/30th sound and look good. Lenses are clean and clear; no haze or fungus.
A Rollei Planar with a solid meter? Worth it, and worth the CLA! You'll be set for the next 10 years, at least! Includes a shoulder strap with the correct quick-detach Rollei clasps!
Asking $900, shipped in CONUS. Zelle or Venmo.
