Okay, so i got this huge lot of Mamiya parts (two backs, four lenses, wlf, ae finder, grip, everything!) but the body mirror/shutter is jammed and i think i did stuff to it i shouldn't have done, it wont work anymore.
Summa summarum: I need a Mamiya 645 body. Sell me one, please.
Edit: As i learned (thanks to Tkamiya) i can even go with a Pro or Pro-TL body, which supposedly is better, i guess i would prefer that! So, yet again, let me know what you have got.
