That's Jonathon Marshall of Marshall Models. He's 100% legit. After the fiasco with He-Who-Shall-Not-Be-Named with the 1/537 Excelsior kit, one the victims bought Jonathon's 650 Enterprise-E kit, got it and started working on it. As they talked, he convinced Jonathon to do Excelsior, and so we now have a legit 1/537 U.S.S. Excelsior kit with decals printed by Microscale (art by yours truly). We've also got a 537 Enterprise-B, and 1/350 versions of both ships, as well.
Jonathan's going through a rough patch right now, so it may take him a bit to respond to stuff, but he's shipping.
