I seem to be nearing the end of my petzval stash, and it's a rainy day, so here go a few of them... There will probably be a few listed at once, so please be specific on which lens you mean if you have questions.
This is a Bausch & Lomb projector petzval lens, marked 4.5" focal length. Suitable for 4x5, would vignette on 5x7. Elements unscrew easily for cleaning or general messing around with it. Front element has a small approx1mm ring of edge separation that wouldn't affect photos. Otherwise, glass is good with normal cleaning marks.
About 2 1/2" tall, 2" in diameter overall, weighs 9.9 oz. The glass is about 42mm in diameter but there is an internal ring that restricts it to about f3.5. If you dremel (?) out that ridge, you'd get it to about f2.7.
Price: Was $85 shipped in the USA. Now $70 shipped anywhere I can send First Class Int'l Package rate. USPS money order preferred.
