MPM 1/72 Fokker G.I Mercury

A Mercury VIII engine installed in a Bristol Blenheim I; this is the same engine as installed in the G.I. Note the white or light grey baffles between the cilinders. The inlet tubes for the oil cooler can be seen on the left; they are in the 11 and 1 o'clock positions on the G.I. Both inlet and exhaust pushrods run together in one oval-section tube, slightly thicker at the root. The vertical tubes alongside the reduction gear are absent on the G.I. The exhaust tubes run forward into a circular collecter pipe that forms the front of the cowling; the installation on the G.I is very similar. A difference is the way the heavy circular exhaust collecter pipe is supported; on the Blenheim short light grey tubes can be seen besides the top propeller blade and below the other two blades. On the G.I. this struts are longer and thinner, and generally more prominent. The propeller and hub look very similar to that of the Fokker G.I.
