They were made in Germany - I’d say 2005-2010
there were A few models, the Jay Tee (a Jazz with 3+1 headstock) and a model called the spitfire which was like a chubby Jaguar with a mm/p configuration.
They exhibited at bass day UK in around 2007.
I had it in my head that they evolved into another brand and disappeared.
They were nice basses. And this is a bargain.
