Here are some photos of Bob Smith's CLW etched-side ALCo passenger units with added details, including revised windshields on the A-units, with the proper shape made by overlaying thin brass on the original bronze casting for the cab. I've read that Bob wouldn't admit that the windshield shape was incorrect, but I never tried to discuss this with him. I visited Bob one time in the 1970s in Florida, where he appeared to be running his business out of his garage. His E-unit Blomberg trucks were designed with an equalizing mechanism for all axles, but it was a little tricky to assemble. I built some F-7s and I had the kits for the transfer unit, but never got around to finishing it.
