[Milsurplus] PRC-74B & SEG-15D help request

[Michael Tauson]

Hi, folks,

Would anyone out there in the audio radiance be able to help me with a
few minor problems?

RE PRC-74B: Does anyone have the specs on the coil for the AS-1887A
antenna so I can make my own?  Also, does anyone have any spare mates
for the PRC-74B battery connector or know where I can get some?  And
finally, the manual indicates the PRC-74B can be used as a vehicular
radio but I cannot find any mention of any sort of a mount or other
provisions.  Has anyone seen anything that indicates how this was
accomplished?

RE SEG-15D: Does anyone have any RACAL antennas and/or audio
connectors for this puppy they'd be willing to donate to a worthy
cause in exchange for a contribution to their own "cause"?

RE MS-53 & MS-54: I know the MS-53 sections are stackable but I read
what may be a misprint that suggested the MS-54 sections were
stackable as well.  Were they?  Also, what are the chances of finding
a base to match either of these sections?

Best regards,

Michael, WH7HG
