If you need a Bay-60 filter, this is what I have:
Hasselblad Bay-60 UV-Sky 1x (Germany). Edge lettering worn. Good condition with light coating marks from cleaning - $18
Hasselblad CR 1.5 (81A) Bay-60 light balance filter (51614). Excellent, in the box with the original instruction sheet - $25
Hasselblad Bay-60 linear polarizing filter (3x, -1.5) made in Germany. A few specs of what may be dust between the glass layers, but quite clean overall - $32
Hoya Bay-60 HMC UV (0) (Japan). Good condition with the usual coating marks from cleaning a Hoya HMC filter - $11
Plus actual shipping, payment through PayPal. I'm in New York.
