Hello Ara;
Did you find a case yet? If not, and if you know some one handy with a TIG welding torch, have them build up some material on that side of the case, then grind to shape, and carefully file to a flat surface again. I have two of these engines brand new in a box that I bought from John Lowery and Betty Fox when they made a trip to St. Louis years ago for one of our contests. Betty used to have a sister that lived here. Anyway, if you have any interest in those, drop me a line.
Type at you later,
Dan McEntee
