Well Rod, I've rested up and have read your post about the Chatham roof-line several times while refering back to the Chatham site with the early pictures. Excellent sleuth work indeed. Thanks again for taking the time (and patience) to get to the bottom (or is that the top) of this. Sometimes my brain is alittle slow to catch up, the pictures helped immensely.
Now, does anyone have some glue so I can re-attach the tower on my HL piece??

Ron
