[Boatanchors] R-127/CRD2 Bearing Indicator Receiver

[John Hensley]

Brian, at the US Library of Congress Tech Archive I found these two listings:
11-513Radio Set AN/CRD-3.  War Dept.  Jul. 1945.  280 p.U408.3.A13 TM 11-513 Jul. 194511-514Radio Set AN/CRD-2.  Dept. of the Army.  Feb. 1950.  259 p.U408.3.A13 TM 11-514 Feb. 1950
If anyone has a copy of TM 11-514, please speak up.
Thanks to all for the interest.  I just want to find this radio a good home.
