After seeing the Cruver model United DC-3. I started wondering about the door on the starboard side. I checked period photos and the United DC-3 with that livery did have a entry door on that side.
Some 1930s period photos show starboard entry and I have seen others of period American AA that also have the starboard entry- and just to confuse the matter further-elsewhere there is a photo of an early United DC-3 with a food service van on the port side and passengers getting on on the starbard side. Food service guys aren't going to carry stuff around the tail so there must have been a door/access on the port side as well.

http://www.airliners.net/photo/United-A ... H/0137434/My 3-43 Cruver C-47 has one on the port side. I can't tell from my photo if it also had one on the other side. Perhaps there was an earlier ID? The later Korean war edition has the large port cargo/entry door.
Was the Cruver United DC-3 issued with those antennas and DF that are on the Cruver ID?
Bryan? Dan?
Most all aircraft have passenger entry doors today on port side{ and other access doors on the starboard side}.
Could some one look and see if there was one on the other side as well or was the United one an earlier model. Bryan? Dan?
