I figured I'd mention this. I picked up a 1962 Panasonic tube table radio while visiting a friend in Montreal while at a flea market.

All other older Matsushita electronics I saw there were labeled either National Panasonic or National. This radio just says Panasonic, no mention of National on it anywhere.
