Here is a unique photo. I located this engine on a safari in the northern Transvaal area of South Africa, near the village of Messina.
After nearly a full day of negotiations, I was unable to purchase it. However, I won't give up!
How I'll get it back to the States is another question. Anyway, I think it's a great snapshot.
The engine is a Petter, 7 HP, Patent Diaphragm Pump. No other tags or serial numbers could be seen.
