Al. I'm afraid I don't have the exact measurements you're looking for. When Stevo del & I were out there last Fall I did measure lots of stuff, but found the Maxwell drawings to be quite close- or at least close enough for HO! The only problems Maxwell gave me were things like the 4 vs. 3 steps in the top of the South wall, the missing window on that wall, etc. An old trick you might use, if you have sharp photos, is to count layers of bricks to gauge height. By the way, I've changed to a Grant Line 5010 Roundhouse Window- the panes are right on, you just have to cut down the frames. SR
