FSV Chassis(?) ID help

Sorry for the "cross post" but I ran across a D-Sports Racer / B-Mod Autocross car that upon further inspection appears to be based on an older FSV chassis. Rather than start a new thread I am referencing the original in this forum to seek some help. Please see the original post here:

I have an agreement to purchase the car, but would like to try and ID the base chassis before completing the transaction. Thanks for any help.
