Antony Charles Tomlinson, the luthier/artist behind British Custom Guitars has been designing and building custom guitars since the 1980s. His instruments are unique, and some of them are more like pieces of art than instruments. In future Tomlinson's design efforts will be split between 2 companies, the first customising and creating more standard forms of guitars for British Custom Guitars and the second creating very unusual (but still playable) guitar art under the name A.C. Tomlinson.

Atlansia is the brand of Japanese guitar maker and genius inventor N. Hayashi, and has been active for at least 40 years. Also makes guitar making machinery. I cannot find any distributors of the Atlansia brand outside of Japan.
