[MRCA] RT505/PRC-25 Manual needed

[mr3hi8st8or5y at cox.net]

Hi Gang,
A friend of mine is working on a PRC-25 that has mods not in the manual. He has TM 11-5820-398-35 dated 1963 which does not match his newer RT505/PRC-25. Ser. LBAD-2961, Order # 36039C514530E U.S.
Reconditioned at LBad, it might have been for use by the Marines. I may be able to buy the Change 1 addition but what may be needed is an MWO (Modification Work Order).

 Do you have a newer manual?  Please respond off list,
Roger
