Very nice! Back in the late 60's I took a Monogram 1/48 Spit IX, "converted" it to a Spit V using Monogram Hurricane exhaust stacks and a three blade prop, vac-formed the canopy and opened it as well as cutting out the door. I clipped the wingtips and faired them in with Testor's putty. I put a bogus desert camo paint job and USAAF markings on it. Not much by today's standards, but I was pretty pleased with the result. Not accurate but pretty. I wonder where it is now? I know I did not throw it away.
Did you consider forming a Abouquir Filter for it? The original desert filter is as ugly as sin.
Great job!
