You can narrow it down to only 10 issues by referring to the yearly index
in the December issues in those days.

Colin, can you narrow it down a bit beyond 'the fifties'? I have most QSTs
from that era but if you or anyone can narrow it below 120 issues.....
Cheers

Water Cooling:
Jo Jennings, W6EI, installed a converted water cooled 4CX250 in the base
of his mobile whip. He converted. I think Eimac subsequently built some
water cooled version based upon the results. There was a writeup in CQ or
QST in the fifties.
