Vintage Tube Amp

Vintage Model CH30 Challenger 5 Knob 6 Tube Amplifier 1940s? Pictures with tubes and knobs installed and removed so interested buyers could see condition in those areas. Tubes all seemed to match the numbers imprinted on the amplifier. In vintage used and untested condition with signs of use and wear. Has scratches, paint loss, some rusting, the one piece of detached speaker cord/connector looks very worn. Corners all have paint loss and scratches. Baseplate under the wiring has a fragile paper schematic partially glued or stuck to it. I replaced two missing screws on the cover and one screw in the baseplate. Power cord is approximately 6.5 feet long. I had read somewhere if you are unfamiliar with tube radios/amps that you are better off not testing them because you could damage the unit? Unsure if that is true or not but for that reason I have not plugged this in. Please be your own expert when determining completeness and correctness of this piece. I do my best to explain what I see. See photos for condition.
