The roof hump on my units did not show up for years, but was a material problem as you say. Earlier F units had an overhang at the roof line and a flat plane end below it. Enhorning slanted the entire end to replicate the overhang. In some ways, he was ahead of his time, later F and E units had no overhang. His use of less-than-pure Zamak on many castings was a detraction also.

It was a rubbery flexible material that was different than styrene and gluing anything to it was a challenge. In the 1970's I purchased about a dozen or so shells from Claude Wade along with a bunch of mechanisms that he created to convert them to scale. At one time he considered offering an F-unit re-powering kit for the Enhorning shells. His drives featured custom made gear boxes, and 42" diameter brass wheel sets. When the Enhorning shells were no longer available, he dropped the idea of re-powering kits and focused on improving his SSL&S line of steamers. In the dozen or so shells that I ended with, a few of them did not have the roof hump. I ended up with 3 or 4 serviceable units that I painted and ran quite well with the Wade drives. I have some photos around somewhere, and will post them when I find them. Bob Frascella Wenham, MA
