I recently bought an old 9X12cm Recomar camera and can't get film for it (don't have holders anyway). I have heard that one can devise an adapter to fit 4X5 film holder on the 9X12 back. Does anyone know about this conversion? Are there any commercial versions out there? 4X5 is just a tinch larger than 9X12cm, I think. Thanks for any info or ideas. Ken Brown email@example.com.
