recently bought this stanley clarke deluxe and want to check its authenticity.

Welcome to the forum.. Do you have any pics of the bass you can share with us ? Preferably front and back plus inside the electronics cavity so we can see if it has the original alembic gubbings inside.  
From the serial number it shows it's a 1993 Stanley Clarke signature bass
