I know that Doug Hewson wrote some fully detailed construction series in Engineering in Minature for various wagons. I dont have them, or rather, my EIM's are not where I am right now, but I am sure someone on the list will do. Although his designs were 5", I am sure they could easily be modified to 7 1/4" or whatever. And, wasnt there a wagon design in a Model Engineer a few years ago? Alan.
