Radio ID

I know Wards Classic Radio used to have a good summary of radio identification, but given they have closed, site is not up anymore. Anyway, I am going through boxes of parts and found this radio. Any idea on what it may be from? Antenna is on bottom of radio, but the exposed transistor on the front has me stumped.

Thanks

It is from an E-body.

Thanks, I didn't think to check your site there. So its for a 70 E-body, sales code R11, 2 watt Music Master. Some power those old radios had, lol. Now to decide what I want to do with it. I have a 70 Challenger, but the build sheet calls out an 8 track AM. This radio is rough. Cut wires, missing knobs, etc. Not sure it is possible to restore it.

Looks like it may clean up nicely. Maybe a good core to get rebuilt with modern internals?
