Was that a "film back adapter" or a "film pack adapter"? The former might be a Graflok back, which will come in real handy for using Grafmatics. If you have never used a Grafmatic you are in for a treat. 6 shots in the space of two film holders; change film in a wink, automatic numbering of each frame. I own half a dozen and they are the bomb!
On the other hand if it was "film pack adapter" you have an interesting artifact of a bygone era. Either way, enjoy!
Alas, it is a film PACK adapter, with 4 film packs that expired in 1976. When bidding on the camera I was hoping it would turn out to be a Grafmatic, but the seller was very accurate in his listing. Right now I'm using the 7 film holders that also came in the package.
Once I feel I have the film loading/unloading, camera setup, focusing, exposure and film processing under control, I would like to explore further the Grafmatic back.
