After digging into the wing I’ve found the wing is balsa built, balsa sheeted and covered in what looks like Oracover. The fuselage is maybe a fiberglass mold. There’s a thread on here (Cermark Spitfire) that shows one of the members cut a patch out of the rear of the fuselage to install a pull-pull tail wheel and rudder……
I tried to post some pics, but they wouldn’t go through. Thanks!
