Many of us who build craftsman structure kits employ the technique of adding rows of nails to our clapboard walls. Personally, I like adding this extra detail and I've done it so often not doing it feels kind of strange. It often turns up as a bit of controversy however, among modelers, whether or not nails would be seen on clapboard walls. So when I stumbled across this building at Mystic Seaport, I had my answer to this age old question - sometimes and generally on older buildings. Fortunately I had my camera with me and can put this issue to rest! But the real answer is, when modeling, do what you want to do and enjoy yourself.
The pic above is from a highway overpass we build in our upcoming DVD, Roads & Highways for Your Model Railroad. We've finished shooting today, with just some editing to do. It'll be available in early Septemeber. We'll post a video preview soon.
