Help to identify v12 or straight six castings

[joerom]

I have a set of castings for an engine that looks like it could be made into a straight six or a V12.I have no drawings and need help to identify.Any help is appreciated.At this point I may also consider selling.

From the pictures it appears to be a V12. Might be something designed and half built by some unknown builder. Looks like it would be an overhead cam type aero engine. With the hole in the front cover and the stem in the oilpan it would seem like the glow fuel would be sucked into the crankcase and into the head from the stem in the pan. That is how the 1/6 Cirrus worked.

Cant help with the drawings. Never seen anything available from the casting suppliers.

Hello,
Thanks for your input.I don't know about the aero engine,because the six cylinder block is 8 1/2 inches long and very heavy.When you lay out the parts for the 12,it is very large also.There are parts for both a six and a 12.There are 2 different oil pans,one for the six and one for the 12.Also,there are front and rear covers for the six and the 12.I was told it was a model of a Jaguar type engine,but I have seen nothing to match it.I agree that it would be an overhead cam.
