I just picked up a Manhattan Optical oddity. Looked at all the usual sources (and the couple of manhattan catalogs online) and googled and came up with nothing. It's marked as a "single long focus", 5x7, f16, and No 0. It's from NY, not Cresskill so I don't know if that makes it earlier or later.
Projecting an image on the wall alongside a 12" Dagor, I make it a little it longer and much dimmer. The construction is odd- its a meniscus (cemented doublet), with a half inch fixed stop out front (around an inch or a bit more away). Directly behind the glass is another stop, around 3/4" or a bit more. the glass diameter is around 1 1/2 or a bit more. the barrel and front stop unscrew from the mount. I need to take the mount off the board to see if I can then remove the glass and it's mount. There is a knurled ring which seems to be holding the glass into its mount from the inside.
Anyone ever seen one of these? Know anything about it?
Thanks,
Dan
