I doubt Ryan built any with the Ranger, which was an inverted 6-cyl. inline. The pre-war ST, STA, and ST-M used the inverted 4-cyl. inline Menasco engine.
After WWII, a few ST3KR's (a.k.a. PT-22) had the Kinner removed and the Ranger engine installed. Cleaner lines, a bit more horsepower. Some of these were just as beautiful as the pre-war ships, and a few are still around.
