Really nice classic lens in fully functional Acme Synchro No. 3 shutter. Good for 4x5, 5x7 and some may use on 8x10 (at portrait distance, I suppose). Takes a long throw cable release. Convertible to 14" (356mm) by using the rear cell alone.
Glass is in good shape, some faint cleaning/coating marks on rear surface.
There is a rim dent, but this type of lens does not have threads.
Free bump for a very good lens at a good price. I've used mine at infinity on 8x10 (stopped way down and without movements); as it happens I was printing one of those negatives yesterday and it looks fine.
I think the front element can be used alone too, but I'm not sure what the focal length is.
