Rollex-Patent 120 Roll-film Back for the 6x9 Voigtlander Bergheil Camera
This is a Rada film back which will allow you to use 120 film to create 6x9 and 6x4.5 images with a vintage 6.5x9 cm Voigtlander Bergheil Camera. If you’re not sure which size camera you have, a quick way to identify the smallest Bergheil is to take a look at the lens. The 6.5x9 version is usually (but not always) fitted with a 10.5cm (105mm) Heliar lens.
This film back will also work on many other 6x9 plate cameras, assuming that it requires a holder with thin edges.
The back is in excellent condition and appears to have only been used a few times in the past 70 to 80 years. It comes with its original box which shows some wear & tear, a reduction mask for 6x4.5 and interesting old instructions in German.
