The story is that it is the poor man's version of the Prado. It is the most simple Leitz 35mm projector.
It has heat absorbing glass.
The condensor and the lens can be substituted for a model for 18x24mm (Elmar lens).
The standard condensor and lens, Elmaron (80 or 100mm), will cover up to 40x40mm.
The slide stage can be substituted for a model for film strips.
Lamp would have to be get used or from old stock.
Breathtaking look... Well chip j, in many cases you seem to have a special attitude...
