Hi Mike. I can't help with the references (I'm sure our UK and Empire friends will come through for you though!), but since you opened the door, two things I'll offer: first, best wishes on the venture and thanks for looking out for us; and second, a request--please consider some seated pilot figures for us to show the aeroplane occupied! That would be very nice, as our options right now are limited to the single PJ Productions German and British figures.
Thanks for listening and good luck!
Regards,
Bob
