Default Unknown Model Engine - Oil Recomendation

I've been working on this little model and was wondering if I should run SAE 30 in it or something lighter. Interesting small scale engine with adjustable timing and water pump for cooling.

I have found that SAE 30 may be a bit too thick for models. You might try 10-30 in the crankcase. It will splash at lower speeds and lubricate just as well. Be sure to keep the rockers and pushrods lubricated, as they will wear rapidly if run dry. Interesting engine, do you know who made it?

Andrew;

No clue as to the maker of the engine, I purchased it at an auction in Ohio. The auction had a large number of toy steam engines and a couple of unmachined Stuart steam engines so it's unclear if the prior owner did the machining or purchased it. Thanks for the information.
