Sometimes you just gotta wonder what happened. Herb Shaetzlein displays one of a pair of under-construction two-truck Shays on pages 34 and 35 of the March 1970 edition of Model Railroader magazine.
Excerpt from This is N scale:
“There is one commercial No.80 screw in the model. Except for this, all bodywork and fittings, large and small spur gears, as well as .5mm and .85mm screws, have been handmade from brass. The axles and crankshaft are of cold-rolled steel; Herb formed the crankshaft and gears using a homemade pantograph milling machine.”
If you’ve got access, dig this one out…
