Holley 4D (4 barrel) TBI throttle body

Was digging around in my storage a few days ago and ran across this.
A holley 4 barrel TBI unit. Pretty sure it is from one of their old 4d injection systems.
No idea if the injectors or sensors work. Looks like it had a little splicing done on the wires.
I will include picture of the numbers I see cast/stamped on the unit.
I think I had originally bought this to remove the injector pod, cap off the fuel ports and use as a throttle body for MPFI.
I ended up using a monoblade Tb instead.

$200
