Need help once again on a steam locomotive. Any help appreciated. Can't find any information on this 2-4-4-4 locomotive. Looks like a Marx but can't find anything

Only the first and last drivers have flanges by the way. He previously posted a video of this beast in operation.

I have one of those which is strong by itself, imagine the pulling power!

I suspect there would be some flange resistance on tight curves.
