You might try David Little from Kynamco. I bought a few sets of snap caps and am very pleased with them. He takes Kynoch brass, cuts them down, adds the spring loaded dampener (with screw adjustment) and nickel plates the entire works. I spoke briefly with David and Sue at SCI in January, and he had them in his booth. I assume he still has some for sale.

I can't find his website at present, so try his email at
Kynamco@aol.com

Hope this helps.
