The Franka works in Bayreuth counted until the sixties of the last century to the very successful camera manufacturers in West Germany. Especially famous was the roll film camera "solidarity", of which there were countless variations. The worst of this series made this "solidarity Record B". It came with only one moment of time (1/30) and "B", but had three apertures (8, 11, 16) and the "special lens 1:8 / 80" was probably a doublet. The distance was adjustable.
Two features, however, are noteworthy: The aperture was no pinhole, but consisted of lamellae, rare in this price range. Then there was the possibility of an insertable mask (is it still in my), but also include 4x4 cm negatives. It got so out 4 more images and could also make slides that still fit into 5x5-inch frame ("super slides").
It is worth noting that almost all camera parts from Bayreuth, home of the Franka-work, came: the lens was from Steiner / Bayreuth, the closure Franka developed itself and the bellows is made of Kreher / Bayreuth.
The Franka Solida Record B came on the market in 1958 and was sold in three years 78000 times. The price was 33, - DM
