Thanks, Ed. Sorry about responding so late. I think I am involved in too many forums and lose track of what I'm doing. I started searching for threads regarding aircraft carrier interior bay colors when I saw my post. Crap, it's been a week. I haven't been able to find the Skywave/Pitroad set. I did find a decent drawing with dimensions of the gun, so I decided to make my own. It doesn't look too complicated to make. I made a pair 1/300 scale Twin 40mm AA's, a year ago. That was a challenge. I even turned my own barrels, without a real lathe.
Thanks again, Ed.
Jim
