Hello-
With all this talk of fine crafts and the need for people knowledgable about fading trades, it occurred that I have something in my own possession which may be of help to other groups do wood car repair. I'm in the process of moving to a new place, and in doing so, it reminded me of a set of half-circle stained glass panels I have which came out of a GTW combine, #7293, which was scrapped in London, Ontario in the 1960's. Three of these are complete, and I have pieces of a couple of others that one could fairly easily replace missing slag glass in between and get a full set. I plan on keeping these, but I would be happy to loan one of them as a pattern for measurements for similar cars that need preservation. A picture of these can be found in the Dorin GTW book on page 105, the upper photo, and I would be happy to take shots and send of what they look like now: I use a couple as a backlit transom window in my current kitchen, and they are goin with me ;-).
I am sure there are other examples, but these same style windows are in the Lake Superior & Ishpeming No. 63 at Green Bay, and are somewhat similar to Great Northern #3261 and Lake Superior & Ishpeming #64 at Mid-Continent. Below are the windows from the GN car: put them together (no wood divider in between) and you have what I'm talking about, but more colorful and ornate. They have yellow-brown slag glass, with two thin dividers on either end and a more ornate panel in the middle.
