Good shot out of an oldie. I've got a Duaflex model US model Kodar Lens marked F:8 72mm 3.5 ft to infinity 3Fstops 8, 11 and 16. Where do you get the 620 film for this and where do you fet it developed. If I put 120 film in does it overlap the no's when you rewind or does does it leave a spsce between the images? I'm not even sure if the camera will accept it. A lot of questions but would appreciate any input you have. I've still got three unopened rolls (1964) of verichrome pan. Tnx Carl
