Thanks, friends. Refurbishing these old projects is a very relaxing form of modeling. "Low-tech" modeling like this offers a lot. The old Otaki/Arii kits look pretty nice when finished even if they don't have all the tiny detailing of a modern kit.
I've been doing some thinking about the airplane I modeled and I now wonder if the 1/1 version may have been the second prototype of the N1K1-J. The photos I've seen of the first prototype show a cowling with a much bigger main opening and no chin scoop. Regardless, my model represents some form of development machine.
