Hasselblad B50 Bay 50 Proshade Compendium Bellows -Read-
$24.95 USD
This is a really cool matte box style shade for Hasselblad cameras. It comes with a Bay 50 mount, which fits most of the C and C T* lenses.
This one is in good condition but there seem to be a few small pinprick holes in the bellows. Repair them at home and get a good deal on a nice compendium bellows!
