A friend of mine, who owns a small-town movie theatre, (yes, they still exist) gave me two Projection Optics Co Superlite Series III C (Petzval?) lenses, one a 4 E.F. and the other 5 3/4 E.F. In addition, there is also a Hilux 264 Anamorphic prism which fits the Superlites. Is anyone familiar with these lenses? Any chance they can be useful in some makeshift LF? BTW, I'm torn between using the Hilux as a paperweight or a doorstop, though it occurs to me it might make a very handy anchor in a pinch.
