No, this isn't castings for some strange engine! It is a Tube Bending Set, built, put together and sold by members of the Emerald Valley Model Engineers as a fund raiser. They had them last year, but I didn't make it to GEARS in 2005, so it has taken me a year to get a set. It covers tubing from 3/32 to 1/4" and consists of 12 forming wheels and 6 anchor posts. Now, all I have to do is figure out how to use it! :o)
