I saw this on eBay, and the seller says he thinks it's 1962 because of a date on a service manual... Looks earlier to me, but I have never fooled with one of those so no qualifications in my guess. Looks like an RCA 648-style projection barrel with 5" CRT? Hope it gets into the hands of a collector, and the price looks right!
I have seen 40s models of those, and I think there were even prewar ones. I wonder if this is a 40s one and the seller thinks '62 because of a reprint date on the service manual?
