Early Powerplus Engine

Inherited from grand father, reluctantly for sale.
Engine is disassembled but appears to be very complete.
Bore on both cylinders is standard, small gudgeon pin groove in rear, 5 fins damaged.
Front cylinder has no damage.
Carby is wrong for the model, but was in the box with it, maybe a HD flat twin?
Magneto is Fellows, a proprietary one offered on some models due to Os has not always being available because of WW1.

Engine is in the shop. Contact ParkerIndian.
