I have a Hasselblad CW winder. When I purchased it about 2 years ago, I thought it would fit the 503cx but I was sadly mistaken. I have since migrated to Phase one and still have the CW, 503cx Body and 45 Prism. They have been in a dry room wrapped in plastic eve since. The CW show minor signs of handling wear and about a 7/10 for the mounting area. The remote is in perfect condition 9/10.
Can you use the lot? well make me an offer, as usual I can upload some pic or PM you,
