Interesting that it has a steel boiler, Ken does not mention that in his book, but not terribly surprising that Weeden may have made a few that way.
Is there any evidence of it ever having feet attached to the base like the No.45's, looks to me like a No.7 with a smoke stack added. Can't remember if the steam line had an elbow or just had a bend in it on the one I had.
What I do remember was how flimsy it was.
