Under close examination of the quality control tag, where it say model number it appears to say CT-800 with a small 12" penned in just after.
I asked the seller if he had any history on the set, he bought it at a yard sale in Santee CA, a suburb of San Diego.
the people he got it from said it had been in the family since they were kids, possibly the original owners or at least early owners.
The seller had it for about seven years.
Radiomuseum has this set listed, it looks the same, says 30 tubes with a Tarzian tuner, and chassis# 135, maybe different chassis runs used a different tuner with one less tube?
