At a guess, your serial number is IS00083855.
Grover-era trussrod cover, so likely 1992-1996 (though the shape was used late as 2002 in the BT line). My first guess would be a Mercury, & an MG-20 at that. (rationale -- if indeed an MG, most of that line had Rose, most of the rest had TOM, & a few had Wilkinson, leaving only a model or three with a Strat-style.)
