Duly noted, and thanks for jogging my memory banks! The semi-hollow I owned before was a Shine. The same model is marketed as a Douglas in the US.
The Strat jack was installed at the opposite angle to where it is on a Strat normally:
The pickups were something I rolled myself. I bought a few empty MM-style humbucker shells and installed a P pickup in one, the guts of an Epiphone T-bird pickup in another. That was actually a pretty good bass, and is hopefully still out there somewhere.
Lesson learned, the Jack Casady will remain undrilled. I'm waiting for an area of lacquer re-spray to gas off on it at the moment.
