⭕ It is manifolded for a mid 40s to mid-50s MG XPAG engine. This unit was previously installed on an MG TD and gave very good service and results. The unit is in very good condition and I believe requires very little other than typical lube and inspection to put back in service on your car and enjoy. An article describing the Marshall unit and something of the Rootes blower design is attached below. I believe this is the best blower design available.

The carburetor is an originally fitted S.U. 1 ½ that could do with a re-bush on the throttle shaft, and otherwise is in good condition and fully functional.
