These are equivalents to Heliar's of the same length and time period, but somewhat rarer, and definitely not as well loved (= cheaper)
This one is probably from the 1930's. you could look it up. I offered it once before, made a picture with it, gasped at the quality!, then pulled it from the offer. This lens makes textbook brute force tonality LF and ULF portraits. I would stack it against the 42CM Heliar for quality any day of the week!
So, the Model T is killing me. Everythings more expensive than I thought. $800 for a new radiator! $860 for new tires. $1250 for a fresh motor.........you see where I'm going. Guess I'll have to let this slip from my grip.
Gotta have $385 for this, even with the big rim ding. Sorry, do not have a flange either. I recall, oddly enough, that it fits the big wollensak size, like for an 18" Verito. I can confirm that if necessary.
