The DC-3 was primarily powered by one of two types of engines - the Pratt & Whitney R-1830 (twin row) and the Wright R-1820 (single row). I have reviewed what information I have and a large amount of information found on the interweb. All of the historic pictures I can find of Eastern Airlines DC-3's, all appear to be Wright powered (you can tell from the length of the cowlings).
Post WWII there were so many C-47's (Pratt & Whitney powered) converted to airline configuration, I assume some ended up with Eastern. (Maybe they were converted to Wrights for continuity, but that seems like too much trouble??) Can anyone provide definitive proof that Eastern Airlines operated Pratt & Whitney powered DC-3 in regular service (pictures would be appreciated)??
Please don't show me PBA "hockey stick" 1980's DC-3's or C-47's operated by Eastern for the military.
Thanks in adavance to all you that help answer my query.
