Ugh, this makes me sad. This lot of lenses has been listed several times with no takers, originally at $3,600 plus shipping (showing as $128.70 for me). Now it's down to $600, still no takers. Wonder why?
Vintage LOT Of 24 Projector Lens B&L Cine scope Kollmorgen + Rare Find CINELUX | eBay
If they're in good condition, a few of these lenses are desirable, rare, and actually do sell for hundreds of dollars, or even more if you convert them to mount on a camera. But what's this in the photos, the glass looks all foggy?
Looking closer, there's water all over them. Some are dripping wet. it appears the seller left them out on the deck overnight (I hope just one night!) and let dew collect on them. And these are the pictures they choose to share! No telling what they look like inside.
Maybe you could wipe the dew off and the lenses will be fine, but I really doubt it. I would ask the seller, but I don't think it's worth the risk dealing with somebody so clueless and careless.
