Nprr minitonka

[Mitchg07261995]

I am trying to find information (brueprints, or drawings with dimensions) for the northern pacific railroads locomotive called Minitonka. All I know about this locomitve is that it has 44" drivers, weighs 12 tons and made by Porter locomotive works in 1870 with a 0-4-0 wheel configuration
If anyone could help point me in the right direction, that would be awesome. I know it resides at the railroad museum in delete Minnesota and is on loan from bnsf

Not sure if this will help but it is a start.

It helps a little bit, I could probably use the 3D model to help with some dimensions. What id really like to find is some patent numbers for some of the parts of the locomotive
