Ladies and Gents - I am looking for a Ham-M mast adapter. This is the cast plate that attachees to the BOTTOM of the HAM-M ropttator when you are NOT using it in a tower. A lot of guys have these laying around in the garage. I had one for years in the 1980s but it;s gone now. Anyone have one that they would part with ? 73 de AF4K, Bry Carling
