Thank you for all the replies.
Chessie1971 - Awesome, thank you very much.
Readingfan - after seeing the work done on your engine, I contacted Mr. Wowak before my T-1 even showed up. I will likely have some work done, just not in any particular hurry as I work out of town often, also I just moved and don't have a permanent place to let my girl stretch her legs.
Mr. Melvin - in this case the mantel clock refers to the hemispherical looking bump on the flat surface behind the compressed air radiator but still in front of the smoke box. Don't have a good picture at the moment. As far as I know this would have been to allow for a little more travel of the pilot truck suspension on the 12" to 1' models. My grandparents actually had a very elegant mantle clock in this shape so I guess it just made sense to me.
Gunrunnerjohn - the big trick in this case with a switch for the smoke unit is where to put the thing. The underside of the front part of the engine doesn't have many options. It may involve running wiring back to the cab or even the tender to find a good place to hide the switch.
Overall my only disappointment with this engine has been the sound of steam system - nice for its time but archaic by today's standards. A simple flick of the off switch and things were much better.
