We’ve test fitted this design to the new Eduard kits, but we tried it on the Hasegawa.and AMT short-tail kits as well. It works well on those, too. Then we got lazy: we have so many 1/48 P-40s in our stash we could have test fit it on virtually everything released, including, B/Cs and the long tail variants. But we had models to build so we just assume it will work on them all. When Eduard releases their P-40N this summer we’ll test it on that and modify the design if necessary. Until then, we’ll pull it out anytime we build a Warhawk. Or a Kittyhawk. Or a Tomahawk.
