Radio's for Oval window VW's Contd....
The approved radios for the Oval window VW's was the Big M. Motorola product was chosen because it could be fitted in ovals from 1955 to the last model Oval which was 1957. The radios come engraved with the model number on the side. There were 5M, 6M, 7M and 8M model radios. My theory is that the 5 is for the model year 1955 and so on but the 8M would then be for a 1958 model which won't be an oval so the theory falls flat on its face. Anyway it is just a theory but I am happy that they fit thru the model years as the radio I have says 5M on the side (so it would be correct for Shahzeb's Oval but would fit nicely in my car too.)
