Thanks Tag, she does run well on blocks, when weather hopefully permits later this week, I will try on the rails. Video attached(I hope). Forgive the messy desk, but I know where everything is at and my therapist says it an Aspie thing to have a messy work area, but know where its all at. There is a spare tap on the back head where I think I can fit the Regner whistle valve. I will need to source another servo so I can remotely control it. Those who just watched missed out, with some light buffing, she looks almost new with no major scratches in the paint work, the brass shined up nicely and she runs flawlessly on blocks. I wonder how many of these were produced? An old article in Steam in the Garden had some numbers for the real low production models, obviously this one and the saddle tank Monarch were more popular.
