Update: I wrote to G&G and they wrote back. They can do custom cases for $180 each plus shipping or $325 for two plus shipping. Not bad prices. I plan on getting two so that's $162.50 each, plus shipping of course, so maybe another $30-$40 (hopefully not more than that anyway.) Musician's Friend charges $140 shipped but only have 4 color options. I think it's worth a little bit extra to be able to pick from their styles. They'll even do custom sizing if you send them a template.
I asked about a silver case with blue plush interior but they won't do that because that's exclusive to Rickenbacker. So I think I am going to get a cream tolex case with blue plush interior instead for my Wilkins custom. And a tweed case with gold plush interior for my '78 Fender jazz.
