I have this camera and also a 500 C/M and decided that I want to sell the 503 CW. It comes with a power grip with the remote, PM 90 and A12 back. It also has what I think is the acute-matte screen with the central prism. The exterior looks almost new but as you can see in the picture there is wear on the back from the film back and the secondary curtain looks like most Hasselblads. The film back is a second back I bought and it shows more wear than the camera but works fine and I think I changed the light seal shortly after I bought it.
I did some checking on Ebay for pricing but there seems to be a big difference in pricing so I thought $1600 seems fair but if I am out of line let me know. There is no lens with the camera but I will include a front body cap.
Price is net to me plus insured shipping to U.S paypal verified addresses only.
