Well if I'm correct,it is the 50 cal. version. This is the plane that had the chainguns on the left side. I have an old "Puff" the Revell version with no scale on the box. I picked it up at a old hobbie shop here in town. That on has a poor excuse for chainguns. This is what got me to want to build the 1/48 scale aircraft.
Thanks for keeping the odl eye out.
