This is an injection-plastic aircraft model kit.
Adapted from the CMK Kits website:
This kit of the fighter version Ro.44 contains the same plastic parts as the previous, differing just in the fuselage parts. Completely new are the clear parts, while the resin and photo-etched parts are just slightly different. The decals are also new, offering two machines treated in overall aluminum dope. The first machine sports Italian tri-color insignia on the fin, and the fin of the second machine was over sprayed with camouflage color and sports a white cross with a Savoy coat of arms.
Parts come molded in gray.
