Back in 1982 , I was scrounging in HAM RADIO SUPPLIES , a very old business in Richmond . I found a box of approx. 50 of those B set rubber mounts , most had the tags on them still ..never used . I sent the last 6 to a guy in the UK a few years ago.. I gave away many of them. I have the tubular metal mount drawing somewhere ...these came in various forms to suit different vehicles .

The B set was a TUNED system, the coax leads have to be a specific length for it work, it wasn't really a practical system in field use ..too crude and fragile.
