I have a bunch of Walthers 933-3202 Union City Roundhouse used structures that I am using to build a custom structure, See www.trainiac77.com for the latest pictures, but I've run into a snag. :cry: There are some windows that separate the top part of the roof from first sections. I am missing a bunch of these and have been unable to find them any ideas where to look? I suppose I could make them out of styrene strips, but I'm not that ambitious! Any help would be much appreciated.
