National Panasonic

This was possibly Matsushita's first proper radio/cassette design. Certainly the RF-7270 of 1968 was a radio/cassette, but it has a Philips transport. 

This is one big beast of a unit. I doubt it's from 1970 as it shares design cues from the R100 as well as fonts and type faces from the later half of the 1960s. 

It doesn't work, so will need a large amount of repair and restoration.
