Oh man, what a find! It is a National Panasonic HRO series, vintage early '50's to mid 60's. Highly collectible.
This is not a Panasonic/Matsushita radio, it is a US built product from National Radio.
Regardless, it is going to need a lot of restoration to make it worth their ebay flipper ripoff asking price. As it sits I'd be at $300 as Ashley Broad would say.
It is going to need a LOT of restoration and this means time and money. How many folks do you know do that kind of work? Very few good ones left breathing and in active business in the USA, and they can (and do) charge premium. Seller says it "works". Define that. They plugged it in and it lit up. Are they a licensed ham qualified to assess? No, just a greedy flipper turd who wants to cash in.
Don't know about you all, but these flipper ripoff artists are really starting to tick me off. The flipper turd got paid to clean out a house/estate and because "one sold on ebay in 2013 for xxxx" they think they have a gold bar.
