I accidentally typed 77 instead of 78, thanks for pointing it out. The guy I bought it from, his wife worked for Hasselblad a long time ago. He had a few gold kits, and lots of hard to find stuff. Not sure if he got a deal through her or how he got everything. Thanks for the information, I haven't heard about these transitional bodies before. Nice to know not many people have my camera Also since it was the second year of FC production, wouldn't the transistional bodies be closer to 1981? Or do you think they were already experimenting with the successor that early?
