[Milsurplus] Before the 75A1, there were ...

[John Hensley]

I'm wondering if anyone can list the receivers that Collins made prior to the 75A1which came out immediately after the war.

Other than the 70E8 PTO & dial kit, I'm not aware of any civilian type sets.  Therewas of course the mate to the ART-13 and perhaps the TCS set.  There was theARC-21 (transceiver) and its update the ARC-65.
If anyone has a list in mind of the Collins receivers prior to the A1, please share with the list.
Thanks in advance
