Ray,
That is a prototype of what we hope will be the next generation TR 6 Supercharger system.
The first type had a modified Holley 2300 downdraft carb. which after a while did not work so well.
I can't say much more except it is a GM type coil pack ignition with a single point fuel injection system.
Moss has made a special throttle body, it has sensors for throttle position, crankshaft and MAP etc.
The original distributor is in there so the tachometer cable can be utilized.

p.s. It is not on the market yet.
