Identification of 1916-23 Twin Six engine

Posted by Wayne58463 On 2023/10/23 22:09:15

I have what I believe to be a 1916-23 Twin Six engine and I was hoping someone here would be able to tell me how to identify it. I checked the Engine Serial Number Reference document in the FAQs section, but it doesn't show serial number stamping locations for the early Twin Six engines.

The engine's sitting on a pallet in the corner of my garage, upside-down, completely wrapped in plastic, and utterly immovable, so I'm hoping the stamping I need is accessible. (Fingers crossed!)

I don't know if these are helpful in any way, but here's an image of the engine before it was wrapped up, along with a photo I just took of some indecipherable stamping on the bellhousing. The upper stamp looks like it could be a date ending in "19," perhaps dating the engine casting to 1919?

Any help at all is much appreciated. Thanks!
