This week’s freak is the elusive Sekova ‘Vulcan’ model, made in the mid to late sixties. Since ‘99 or so I’ve only seen a handful of these. Two in white, and one in a very red sunburst color. All had tortoise shell pickguards that spanned across the treble and bass cutaways and covered the tops of the f-holes.
This is the cleanest example I’ve seen, and the seller, ‘colmanara’ was kind enough to email me a higher-res picture of the bass:

The most unique feature is obviously the pickguard. The tailpiece, bridge, body shape, headstock shape and control plate can all be found on various Japanese hollowbody guitar and basses. Another unique feature is the white finish, not often found on Japanese hollowbodies.

Jerry Teel of the ultra excellent garage band The Chrome Cranks (from NYC/Ohio)played one. see it featured in their video here:

Unfortunately he was living in New Orleans for Katrina and the bass(along with most of his gear) got water damaged. The neck is hopelessly warped and now it just hangs on his wall.
