The head for a 1932-86 is not compatible with a 1934-50 head. The 1932-86 represents 80-90 Series head which is larger than a 1934-50 (50 series). The 1934-50 head is interchangeable with a 1932 50 series head.

The radio shown is newer than 1934/35. The 1934 and 1935 radios were a two piece unit with a speaker box/ amplifier under the dash and a control head with cables such as Buick35 mentioned
