I haven't had time to do squat with the set except take it out of the car. However I'd wager that this is a working original set. The can't be all that uncommon... The 1958 Zenith I use weekly-ish in my bedroom has never been recapped, nor have any of the other 50s-60s working sets that I have.
I think all of these sets saw semi-regular use, so there were no periods of time spent in a barn, etc. Now, ironically, they sit idle in my house because so much of what's actually televised is crap!
