Taylor's has a "Running Iron" Single Action that is not listed or shown on their Website. Correction---Under New Products there is a picture of the Runnin' Iron & description.
It has a Lowered/Wide Hammer(Like a Super Blackhawk} and a Wide Trigger.
All the Smoke Wagons, Deluxe or otherwise, I have seen look just like all the Uberti SA's, and I have seen quite a few. Don't know where the lowered hammer comes from in their ad's.
