Fris. Interesting but I don't remember. I wonder whether the door was offset to enable cargo/baggage to be loaded in a separate compartment behind the cockpit, similar to the F-27? That would have been useful after DCA prohibited cargo (and natives) on the floor, covered by a net, between the passengers in side saddle seats.
I often wondered why the KNILM DC3's and DC5's had the main passenger and cargo door on the starboard side, rather than the normal port side. The DC3 VH-CXC at Bamaga (originally ex KLM/KNILM) has the passenger/cargo door on the Starboard side.
