Zone VI Cold Light head for 4X5 enlargers. Not much to say about this one – photos kind of tell it all. Comes with a mounting collar, which I think is for Beseler 45 series enlargers (but since I don’t have one to try this on, it’s only a guess). Very clean body, I don’t think this was ever used. Not in its original box, but well wrapped for shipment. Price: $100 + shipping – PayPal is cool – cash in person will get you a little discount and a can of Diet Coke!
