Very interesting. Since I live about 1/3 mile from Long Beach, I'll bounce these names around some of the geez... er, old gents, at Bullseye Sporting Goods next Saturday and see if anybody remembers anything about them. I'm not a native of this part of CA and have never heard of these craftsmen, nor even of Thompsons (have heard rumors of Weatherby, tho).
Did any of them make sporters from actions for their own customers? It always bugs me to see a very adequate custom gun with no gunsmith attribution. Somebody needs to give the guy his due....sometimes that's just not possible, tho.
