Hi - and thank you. I’ll add mite pics, and what provenance I have been given so far. So this should be a TJB. It’s current owner has had it 10+ years and whoever sold it to him had said this goes back “to the 80’s”. Pick guard and knobs have been changed (the iriginals have not been thrown away thi, but I haven’t them to hand). Tgise AJBs in the catalog picture do look the part, but I know nothing about these.
There is “Made in Japan” in the bottom of the neck. A little dent on the edge of the body shows the colour is original.
