The model name is probably BC2E-Custom, a custom made guitar. 

 

The letters “BC2E-N” are scripted in its neck pocket.  A piece of Walnut slab is used for its body. It’s luxury.  Three BlackLabel pickups are mounted.

 

In Nov.1989 catalogue, I can see the Stratocaster with tortoiseshell pattern pick guard which is similar to this one.(see below)

 

In this catalogue I find 2 Stratocasters and 4 Telecasters with same patterned pick guard, and also confirm no same pick guard on the catalogues of other period.  So I can tell you this guitar may be a product of 1989 around.

 

Walnut models with metal pick guard are on the catalogue of Nov.1984 as BC2-0131E, on Nov.1986 as BC2-130WL.  Their price are both 130,000JPY.   The price of this one may be similar to theirs.

 

The model name “BC2E-Custom” is only listed on at the end of the catalogue without price description.  The body material is described  “special”.

 

Sound character is warm  like a temple block on low frequency range, and cool like a bell on high frequency range.  This guitar will heal your tired mind.  I love this one playing with clean sound.  3.67kg includes strings . (updated 2021.1.1)
