A friend was at our favorite new/used camera store in Houston yesterday. He called to ask if I needed anything. I rememered needing the Bayonet 60-67mm filter adapter. Bingo! They had a new old stock Hasselblad adapter in the paper box and the plastic filter case (looks a lot like a B+W box made in W. Germany which dates it kinda). Original price: $49 maked down to $29. It's mine. It has a 67mm heliopan filter on it now. I'll know tonight if it also fits the CFE 80mm Planar. There's no reason it shouldn't. Now I can get a hood on the lens and hopefully stop some pesky flare.
The last one I saw at KEH with shipping was very close to the same price.
