[Milsurplus] More TCS questions

Mon, 8 Dec 2003 13:41:30 EST

Fred,

I couldn't recall whether the shorter whip was 15' or 25'.  But all of the 
ships still in commission that I was ever on (except the Bushnell) were built, 
or at least commissioned, post war, and I don't think I ever saw the shorter 
one.

The LCI could have used Mast Base MP-68 with 3xMS-116, MS-117 and MS-118 as 
they came into service in '44 with the SCR-694-C.  But it was more likely to 
have been MS-53 through -49 on an MP-48 or more likely MP-57.  If you remember 
the mast base as having an exposed spring, it wasn't MP-68.
