[Milsurplus] Collins military transmitter

[David Knepper]

Who can identify the Collins transmitter made in the 50's that featured autotune using a 4-1000A modulated with 4-400's.  This transmitter is being sought after by the CRA advisory board for its collection at the Collins Radio Center.

Someone years ago told me the model number and, yes, I misplaced the paper.

The cabinet is gray and stands six feet by about 3 feet or more.

Thank you.
