He'll drop the price down on a day to day basis.

Seller knows how to measure FL

Doesn't mean that all three pieces of the glass are original as the FL is indeed long for the size of the lens itself.

OTOH, my 24" F6 Willard lens is only 10.5" glass to glass, so, it all depends.

I've never seen an American radial drive that size with that long a focal length. Back in the day, the slower Petzvals were the Dallmeyer D type and just a few others. They are pretty long (focal) to their size. Never seen an American like that, though my 24" CCH is slow, it's still huge. Your Willard may have been altered later (new glass) for some reason. A few were used in telescopes for example, and they are documented as having been altered later for that repurposed use.

I've been wondering if the focal length measurement was mistakenly taken from the front of the lens, which might put it closer to the expected value for a lens of that size. But I'm having a hard time believing that mistake could be made from someone selling a lens like that... it is amusing to watch the price drops. Wondering how low it'll go before someone finally bites on it.

I think I remember the seller is the heir, not the original collector, and is going by what was written down. As to what it will sell for my guess is $4,000 or so. The most I would pay is probably $1,800. I already have a great 12 inch lens, an 1862 Voigtlander Petzval. I got quite a deal on it. Seller was using it on 8x10 which it covered, sort of. I think it's a whole plate lens. I'm using it on my 5x7 Korona. Had to have a custom lens board made for it as the flange is nearly 6 inches.
