Some of the old-school ham radio suppliers sell/stock Daburn porcelain
insulators, or you can get them direct from Daburn. e.g. Daburn 10-52:

My 160 meter ATU uses an old military box with the original behive feed
thru insulator that is starting to crumble. I haven't been able to find
a pocelin feed thu of that size (about 3'') and the ones on e bay are
very small. Any suggestions for a source?
