I came into possession of a Kodascope Model B `6mm film projector from about 1928. I believe it has been sitting for several decades and it appears to be locked up. As an example the lens focus was bound by old lubricant so I applied some WD40 and it freed up. From the instruction booklet I believe the film can be manually advanced using a knob in the film loop. I am not sure of this or what the expected operation of the projector. Does anybody have a breakdown of the projector. I believe a good cleaning and replacement of the lubricant and some fresh wiring will make this a usable projector. Any direction or suggestions would be greatly appreciated!
