I don't have it back yet, but I need to give a shout out to @Bruk for the work that he is doing for my on my T1. Maybe he'll jump on here too if I miss anything.
He basically gutted the electronics to make it function as a Legacy engine, added whistle steam, shortened the draw bar, which always bothered me and weathered it. He's great at fielding mundane questions from me and is just an all around good guy. I can't wait to run this around the Christmas tree this year.
Thanks again, Bruk.
