Here is another good reason to go to shows. At the WRIC Winterfest show this weekend I bought this bracket with three really interesting Pittsburg signals on it. You don't generally find stuff like this on eBay. It was originally found at a flea market. They look similar to U-241s but the skirts are about half an inch shorter.

Note: From looking at photos, Elton thinks these are New Lexington and he will reinstate the number U-255A, which was merged into U-241 during his U-Chart reduction project.
