I sold off my Hasselblad 503 and have a few things left over.
A12-6x6 film back. I'd say this is in excellent or excellent+ condition. Have a Hasselblad box for it, but it's not the original box for this back. Asking $200.
B+W 70mm UV-Haze Filter. Bought from BHPhoto and never put it on the camera, I think. Best offer.
Artist&Artisan small strap. This is the braided, Japanese-style strap. Something like 10 inches long. Has the Hasselblad clips. Best offer.
Extension tube. 55mm. In excellent+ condition. Best offer.
Extension tube. 21mm. In excellent condition. Best offer.
Hood for 100-250. In like new condition. Best offer.
