Hi; I have a couple of questions. What are the serial numbers of camera body and back (really only need to know the 2 letter date codes like EU, or EP, etc.)? Does the film insert match the back serial number? Could you ad a few pictures of the back of the camera with back off so we can see the shutter curtain and the front of the film back where it seals to the camera body so we can see any wear there? These are great cameras, thank you for listing. Dave
