I build 1/72 scale. I found a bunch of Tauromodel sheets on eBay for MC200s and 202s.
There really is no good Macchi 200 kit in 1/72. The HobbyBoss requires some gear doors and engine air intake to be created. The old Revell kit doesn't have the right prop hub cast. It comes with a solid spinner-which, I believe, only the prototype or very early production had.
The USAF Museum in Dayton has the one in the top pics. The third is my attempt at an air intake for the HobbyBoss kit.
The last is my initial steps at fixing the Revell kit.
I know Tamiya made a 1/48 scale Macchi 200? Is that the one you built or was there another?
