B&w projector (and TJ-48A) in 1950 movie

I remeber watching that movie several years ago and I remember the tv screen. I don't think they ever really showed the projector itself. As I recall, my thinking was there was no way a little out of the way bar like that could afford an expensive projector tv. I think they just used that type of tv so that it would seem plausable for the people in the bar to see it from across the room. Otherwise, the actors would have to crowd around a small screen set, and that would change the story a little. It didn't look to me at the time to be a real set, but I'm no expert.
