Those golden eagles were a top notch CB in their day. The TR switch cut B+ to the reciever so it didn't instantly mute. Key up and a short feedback gave those radios a very distinctive sound.
The desk mic was a D-104, gold plated with an eagle logo on the grill, best looking/sounding mic ever created.
The bit about the Astatic Golden Eagle microphone and the Golden Eagle radio depends on the year, Mark of radio, and (more importantly) options.
The original Browning Golden Eagle CB, the Golden Eagle Mk II, and the Golden Eagle Mk III came with the brown, Browning Labs supplied, Electro Voice made, "banana" mic, and the GE Mk IV CB came with the Turner +3 style Browning 776 mic.
Starting in 1969 Browning Labs offered an optional GD-104 golden D-104 with the Mk II. I have been told that GD-104 remained an option for the rest of production, but it is fairly uncommon today.
In 1976 Astatic started doing a series of D-104 (T-UG9) microphones for the American Bicentennial, a silver mic and a gold mic (20k gold plated), both with eagle and shield on the back of the mic element. These were called the Silver Eagle and the Golden Eagle. People grabbed the the gold ones up and naturally started using them with Golden Eagle radios. I have been told 10000 numbered gold mics were done (I have no reference to corroborate that number, but do know production was limited and each one serialized), but the Silver Eagle continued in production for many years. The Silver Eagle later became available with the T-UP9 (bottom push bar) stand.
This (late 1975 / early 1976) was the same year the short lived Golden Eagle Mk IV 23 channel radio came out, but those microphones continued to be made for several years, and covered all the production years for the Golden Eagle Mk IV 40 ch, and both versions (Browning Labs and post Browning Labs) Golden Eagle Mk IVA's
It turned out it was generally a bit cheaper to buy the regular Astatic Golden Eagle microphone than to buy the Browning Labs specific GD-104 mic, so most people went with the less expensive option.
Years later, 1993, a "Diamond Eagle" microphone was done to celebrate 60 years of Astatic. This was a brass (not gold) Eagle microphone, that is gold colored, with a diamond chip above the Eagle on the back plate. But of course this was long after Browning was no longer doing CBs.
