+1 for PBY, but then, I say +1 to just about anything new added to the game (Ewwww...shiny new thing!). As an add-on to ports, I believe it would see some regular use, even today. Having said this, I think it can wait until submarines are added to the game. I'd give it a special ability to spot submarines at a greater altitude/distance than other A/C (Doesn't the Storch "sees" GVs at a greater distance than other A/C?); and it would have depth-charges, which most other AH aircraft can't carry/deploy. Adding the ability to carry troops would further enhance it's appeal in the MA (and it was armed for self-defense, giving it an edge on the C-47), and of course, it would fit well in numerous scenarios. Many of our A/C are primarily there for scenarios (how often to do you see someone (other than me) in an I-16 in the MA?), but the features I mention above would give it practical utility in the MA, as well.
