Welcome here at the forum, Iceman19 + thanks for the pics!
What you've got is a Vantage Avenger - but I'm afraid noone here could give you detailed information 'bout your guitar, because the late japanese/early korean VANTAGE years are still lying in the dark...
The (japanese) Matsumoku years of Vantage guitar production came to an end in late '86 /early 87. In this era some of the guitars were made not only by Matsumoku but also by "Cushin"/Japan (or other companies) - then the production of VANTAGE guitars moved on to korea.
The neckplate on your guitar says "No Matsumoku ". If it wasn't made by another japanese manufacturer like Cushin (in 1986?) this Avenger is most likely from the early ninetees - made by Samick / Korea.
that's all the info I can give you at the moment - but we're learning and learning and....
