C2j....I've now looked through the Eastern DC-3s tail numbers 10000-39999 and they're all built with Wright engines except 16070-16072 which were briefly leased from United in 1938.Eastern plainly had a strong preference for the Wright engine DC-3 and took several back from the RFC post-war which had been impressed as C-49s from American, TWA and Delta.
So the 10 listed * are the ones to look out for in photos...I think there's a good chance Eastern did have them converted to Wrights.
