I'm interested in this serial number thing. Until recently I didn't think my 45 DXII (the model without rear shift) had a serial number as there isn't a plate/sticker affixed to the back of the bed plate. However, a little while ago while I was cleaning the camera, I noticed a little metallic sticker on the bottom inside edge of the rear standard, beneath the bellows. The sticker simply has a 4-digit number 22XX on it. Does that sound like a serial number for DXII models to anyone?
