Wanted *Wanted* Motorola MOCOM 70 and Federal Interceptor Siren

[72stormer]

Looking for a presentable Motorola MOCOM 70 radio with speaker and microphone and a Federal Interceptor Siren control with microphone for my 1979 Malibu.

As an aside, what is the difference between a MOCOM 70 and a MOTRAC other than the name and the two switches on the face plate?  I've seen MOTRACs like the one picture below with a slider switch at the top of the faceplate and others with a 4 channel knob.  Would one radio be more accurate over the other for my car? Are the trunk modules interchangeable?

Thanks

the slide switch is for the "extender circuit" which was on low band (30-50 Mhz) models, noise blanker, I think.

The rotary knob was for multi channel models (4-8 channels) There were also 2 channel models, with a toggle switch to change channels

The major difference between the motrac, and the mocom 70, is that the motrac had tubes in it, and mocom 70 is transistors.

  I will look in the pile, to see if I have something suitable.
