Years ago, there were Doves in commercial service with two tiny airlines from BKL in Cleveland. BKL had a small commercial terminal but was never able to sustain commercial service for very long simply because the main airport, CLE was so close and Cleveland never had enough traffic to support two commercial airports.
Another carrier operated a commuter service in Allegheny colors to small Ohio cities from CLE using at least two Doves and a Herron, based upon the number I saw on the ground simultaneously.
IIRC, all of these had been re-engined with HO powerplants.
Nice to see a group dedicated to keeping a few Doves in the air and out of the scrappers.
