Anyone know about this monster? Couldn't find much about it searching. It's a Bausch & Lomb Balopticon Type 41-23-82. It has a U.S.N. (Navy) serial tag as well.
The light comes on, but not the blower, the bulb rear reflector is losing a lot of silvering. There is a wood slide holder/magazine, and an adjustable wood/metal plate holder that fits in the bottom. Any use for this machine aside from its lenses (assuming I have no lantern slides)?
From a distance, I thought it was a Big Bertha. I got it for $65.
The big lens says 18" E.F. and looks to have 3 element pairs. It is 4" diameter, and the barrel is 7.5" tall. It seems pretty clean, and would be even more should it be taken apart and cleaned.
The small one says Sunray Wollensak 4" Focus Back. The front element comes off, and the long steel tube screws apart to reveal a rear element.
Any info is appreciated, especially on the 18" lens. Is it a Petzval? Is it f/4.5? Coverage? It's too big for my iris clamp, how to mount it?
I would use it hopefully for 8x10. Would using its "turret" help reduce required bellows draw? How about screwing the turret onto a lens board?
Thanks,
Bill
