Hi, I purchased one of these for $50 at a local antique shop today. I can't find much about it on the 'net, so I'm assuming that it wasn't a very popular model, but it's just cool to me

I'm not sure what year it was made, but I'm guessing sometime from '48-'52. It doesn't work and it's missing a few tubes, so I'm not plugging it in until I have it looked at. Does anyone have any info about this particular model?
Thanks, Darryl
