Fiddlers Green Ryan STm
James Merrigan

Fiddlers Green offered a paper model of the Ryan PT-16 Trainer which was the military version of the STA, Ryan closed in the front cockpit and added two .30 caliber machine guns to the wings and sold about a half dozen of them to Guatemala as a light fighter. I scaled up the Fiddlers Green model to 1/32nd scale modified the model and built the Ryan STm.
