Ideal Air Cooled - Lubrication?

I have what I think is a 1 HP (11 inch flywheels) Air Cooled “Ideal” Gas engine. Model ???
It has no magneto bracket and is missing the crank case cover. It has grease cups on the main bearings, but the connecting rod big end only has 3/16” holes top & bottom for lubrication. Most single cylinder engines I am familiar with have a hole in the piston to allow drip oiler oil to find its way to the wrist pin. This piston has no hole. There is no obvious surface on which a crankcase cover could seal.
Question: Did any of these engines have a wet crankcase with dipper oiling? If not, how is the connecting rod and wrist pin lubricated, and why does it have a drip oiler?

I tried to attach what I am told is an Ideal engine with exposed crank. Ideal seems to have had some trouble settling on a design for their air cooled engines since there seem to be more than a few. I have an R that i am working on now, useful info is scarce for these, here is one source that I have used. https://www.old-engine.com/ideal.htm
Bare in mind there is no way of knowing what previous owners did to your motor so what you see may not reflect its original appearance.

12voltdc..... The engine pictured is not an Ideal. Pretty sure it is an early Nelson Brothers. Any chance that it might be available?
