Bump, price is $5500, free shipping, I have had two buyers that did not pan out (nothing to do with the back itself, one was a scam I believe the other couldn't find an ALPA servicing center to fit the back to his 12MAX for a good price)
Message me for serial number or any other info
I am also incredibly willing to trade this for a blue right Schneider 35LS lens, although I doubt anyone to has one wants to let it go
