Looking for information on Travler Model #7055 Vintage Turntable made in Chicago

I have acquired a vintage tabletop with case turntable made by Travler Model #7055 and need some information on it as it came with no manual or information? I would like to know if it is a tube unit, mono or stereo, type of needle/cartridge also what would be compatible today (needle/cartridge wise), age and estimated price? Also any places/websites where I could find more information on it?
