Pilot "Portable" TV

[Hambone]

I am new to this site but found it interesting. I have a question or two about an antique TV I picked up over the weekend at an auction. On the bottom is a paper label that reads "PILOT MODEL TV 37U Portable TV Receiver". Additionally on the label there is a list of about 15 tubes. The case is about 15" wide, 15" long and about 10" tall. It plugs into the wall. Channel selection is by a tuning dial like an old radio not a rotary tuner. The picture tube is round about 4" in diameter. It weighs about 15 lbs.
Condition is complete and VG, surprising since the case seems to be a heavy
hardboard material that would easily damage.
Questions:
Can anyone tell me when this was made?
Is it safe to turn ON or best left alone?
Doesn't it seem like a joke to call this a portable?
Does it have any value?
Thanks for your help.
