Need instruction sheet for stewart VO1000 switcher?

Question

Northern Pacific pictures of switcher might help

Answer 1

Stewart Baldwin DS-4-4-1000 best I can do.

Photos are even harder.  I recently decided to add the Big "G" to my plans.  Lots of GN transition era stuff out there, so I am including it along with SP and McCloud River Railroad operations.

Keep in touch.  I'll need some reference material as well.  Let me know how else I can help.
