FWIW, virtually all "California-style" jigs are still made in USA.
Popular brands like Tady, Salas, Sumo, Kicker and others are pretty much all made in California, although in a few cases part of the manufacturing process has moved to Arizona [or Mexico] due to strict new EPA rules regarding chrome, lead, paints, etc.
I'll put something together tonight and send you a picture. I also just sent you an email about something else.
