As I recall all the above is correct. What also did not help the situation was that up till the introduction of Jets, crews were dual endorsed.
At the time Joe was the DC3 Flight Capt and probably only flew the F27 enough to keep himself valid.
Crews were DC3/DC4, DC3/Bristol, DC3/F27, DC4/DC6, DC6/L188, Visc 700/800. Apparently DCA would not allow this on jets fortunately.
