I recently acquired an old mama 6 foldout, which I believe dates from the 1940s.
The bellows appear top be in good shape and the shutter sounds accurate.
However, the focusing wheel gear doesn't budge, except slightly and grudgingly. I'm hoping that there is a release mechanism that I haven't been able to see, and isn't mentioned in the booklet. However, this seems doubtful.
Neither Mid State Camera nor SK Grimes, both in my home state, are familiar with this model.
Any advice would be appreciated as whether there is a release somewhere, or who might be a dependable repair outlet.
Thank you,
Jim Benson
