I have one, purchased several years ago. Not at home currently so can't share a picture. As I recall, it is a traditional locomotive, but a 4-6-6-4 configuration with a "super" motor. It draws a lot of current and will blow a 6 amp fuse but would run on classic AF track. He also put a table top whistle in the tenders. Fantastic workman ship. When I get home, I can find my records and l get you a name. He made several other special unique configurations. I count myself lucky having one of his configurations. Since I haven't seen any more listings from him in a long time, I assume life issues precluded continuing his contributions to the hobby.
