What years were the generators gear driven off the front of the engine with an integrated distributor?

Did they ever use an Autolite IGW 4179 distributor?

A friend, former neighbor/current Landlord of the famous ODSS "OR" has this interesting specimen we looked at last weekend.

It appears to be an early 171. Milt says his dad and his uncle (both Old Order Mennonites) needed a 10 hp engine to run a wood planer. All they had available was a Chevy 171 engine (probably out of a 490 car). The engine was 20 hp. They didn't need 20 hp. They needed 10 HP. So they cut the back half of the engine off. They cobbled some other things onto it (like the Ford Model NH carburetor from a Model T). Not sure if the dizzy is original to the engine or another add on.

Milt is hoping to get this engine to run again. It think it would be cool to get it running again. Could also be fun to tear it down and see what they did to the crankshaft.

He said it ran the planer great for years.

All comments/observations welcome.

Left side. Notice the Model T carburetor pretty much just bolted to the head.

The flyweel. Looks like they started it with either a hand crank or just grabbing the flywheel and giving it a spin like a John Deere
