I purchased this general store off ebay recently and it arrived today http://www.ebay.com/itm/130607773717?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 I had planed to make flats from it and imediatly took it out to the table saw with this result
I will paint the middle section at least a different color once i get it glued together it is made of plywood and a foam board of some kind which he has milled the profiles into. Overall a great deal @ $129 with free shipping and all the added details. and is an apropriate size for my 1:20.3 layout judging by the scale figures i have placed. as far as i know he only has an e-bay store.
