Here is the best I could do with the mechanism. Lobaugh gearbox, looks like a frame milled from bar brass (easy if you have a milling machine), Lobaugh drivers and main rods, and possibly Lobaugh 4-4-0 cylinders. It is also possible that the front of the frame is a Lobaugh casting, but it is difficult to tell from the photos.
A lot of modelers do work this good and better. I have been privileged to meet a few of them.
