Hasselblad 63 adapter ring for bellows hood. (For the first model where the rail cannot be folded) This ring is used when attaching a bellows hood to SWC, C50, or 60mm lenses. (It can hold a 63 filter) It's a rather old accessory, but it's in good condition. If anyone is looking for one, how about it? Instant purchase is OK. No price negotiations. Please refrain from purchasing if you are overly concerned about minor details. I am listing various Hasselblad items. #Hasselblad #Hassel #HASSELBLAD
