The fact that this has an electric motor and 400 foot reels means that it was a workhorse unit for indutrial applications, but probably not a motion picture theater projector.  It was to show instructional or eductional films and short subjects in factories, union halls, YMCAs and schools that could afford such a machine and the rental of films to show on it.   Possibly a traveling entity of some sort took this on tour to promote a cause or candidate, who knows?  It was for 35mm silent films at a time when the amateur market of 16mm had yet to come about, and parts for this thing are of course near impossible to come by and would have to machined if anything ever needed service.  It either works or it doesnt, and that alone would make a big difference in the price it would go for.  It's doubtful the proper lamp can be found, but that could be changed if you were clever and such.  Something of a white elephant, I'd say.  if you had silent films to show on it, you wouldn't want to risk damaging them in such an unknown and untested unit, that my scratch the film.  1922-25 were probably the only years it was made, and the company did not prosper.  

I've seen the same unit on eBay sell for $150 range.  People collect such things I suppose.  Are you selling this unit?  I might know a buyer if the price was low, a gallery artist who still uses old film equipment in his art works and would get the old girl some love and attention.
