Thanks Cannonmn, those pics are great! That last photo threw me for a good sized loop: I was repeatedly studying, pondering, eyeballing, perusing, cogitating upon, musing on, and just plain staring at the object in that picture, without any success in figuring out what part of that model it could possibly represent; then it finally dawned on me that it wasn't part of that model, it was in fact a miniature of a monitor's turret with a Dahlgren gun sticking out of the gun port.
