Need help identifying a flathead four cylinder engine...

[LadyLapstrake]

I have an engine that I don't know much about. It is a flathead four cylinder that has the casting of "CWC" which I know is from the Campbell, Wyant & Cannon Foundry. The thermostat is located in the middle of the head, and the stamping on the head is 12-18-56. In addition to that date stamping, there is another insignia stamped into the head as pictured below with a hex head. Stampings on the block are REG - 1, K206 CWC and X - 15  -D.

Does anyone have any ideas on which manufacturer used this engine? Thanks in advance.

Having 2 head bolts side by side in the middle of the head is a very unusual feature I think. Hercules seems to be done that way.

Sometimes identifying the accessories ( starter, generator, carburetor) will lead to ID of the engine they are on.

The generator is a Chrysler alternator of the type introduced in 1960 and made until 1969 or 1970. If 1956 is a casting date, the alternator is likely a later addition.

Any luck? I'm having the same issue except 40 years older. I can't find any info on the AR inside a hexagon. Here is a walk around vid of my engine.

The engine looks like one built by Continental. I wish the original poster would have put a photo of the other side. It really helps. I cannot see your video. Post a You Tube link, or post photos of your engine. If it is 40 years older it will be different than the engine in the photos.

If the date of manufacture is '56, it may have been intended for an industrial application rather than automotive.
