Joanie, you are correct.
I will tell you his name is Jim and omit the last name.
He lives in Birds Landing California (just west of Rio Vista about 10 miles). He does exclussive graphics for one builder and one builder only, Junior. He also does fine abalone inlay as an art form. Jim does play accordion, but he plays Irish. The late Ed Luckenbach would play music now and then (Irish) with Jim.
Re: Ed, he studied from Junior on the construction/repair and tuning, on his extended visits to Louisiana.
