A BL1 in excellent condition.  Metal parts are glittering same as those days.  I confirmed that the model name is BL1-21R STR by the neck pocket script.  The catalogue tells that wood material is ash.

According to the website “The Study Of Bill Lawrence Guitars”(closed), this model seems to be produced around 1985.

BiLL Lawrence used good wood, and kept less scattering quality by adequate seasoning, and scarcely use over 2 pieces combination.

Translucent finish called STR(See Through Red) should be adapted to appeal beautiful ash grain.  I heard that ash never have figured grain, but this one has tiger grain around the jack.  Possibly it might be sen(Japanese ash), either the information was wrong.

Ash emphasizes high and mid frequency same as L-500, so this guitar may be suitable for lead guitar player.  The price was 77,000JPY, the highest price among BL-1 series then.  3.76kg includes stirings and excludes tremolo arm. (updated 2021.1.2)
