No ebony board there. Below a board and MOP inlays on an EG58-100 from early 1982. Note that there is no volute on that model.
The OP's guitar has a volute, no ebony board, no waffleback tuners, and no Groove pickups that would be on a 1982 EC58-100.
Lots of confusion for these 1982 customs. You see people list them on Reverb as 1000 Super Real models a lot
Here are examples if the 1982 models with ebony/MOP:
