got a 1953 dumont teleset dropped off the other day

finally got the pics to go with this but I got a 1953 Dumont teleset dropped off to me the other day, the guy never told me how old he just said got a old television to drop off and how much and seen this in his van and told him I would wave the $40fee cause it was a beauty and made both our days.
I am guessing 53 based on research I have done minimally and pics I have seen of other ones similar, no real dates on anything inside just model number, wishing it still had the tube diagram inside cause that would have been awesome to see. plugged that baby in and turned off the lights in the garage and not only did all the tubes glow like it was brand new but the screen even got a white line though the middle and speaker crackled a bit turning the channel dial which could just be blow but I have no tv channel to pick up these days. plus I don't think these old ones had channel traps to stop it all from bleeding over.
what I was wondering for anyone who has done it or restored one of these beauties, if I could use a 300ohm adapter I think its called with the antenna plugs one end and coax other end and then plug in either a converter box for tv or just a vhs player to see if it fully works ?
