Many Retina cameras have subtractive film counters and once at #1, the camera "jams". Look for a release,a lever or button to reset the counter to 14, 26 or 38. The 47mm f2 Ektar is a fine lens and was fitted to the 828 filmed William Dorwin Teague designed clamshell Special with either Compur or Supermatic shutter. Possible someone with skill, did a "swap".
