Complete canopy framing for use on the inside of the Hasegawa 1/48 TA-4 Skyhawk kits including our set 48131 TA-4K KAHU cockpit set and if you have 48056 OA-4M conversion it will work on that as well. There is no other set of this type that we are aware of and it will add that much more enhancement to the Hasegawa two seat Scooter kits.
