Amoskeag self propelled pumper photos, etc

Seeking photos or drawings of the drive setup on the Amoskeag self propelling steam pumpers.
Project is to build a live steam model for a Fire Chief retirement gift (he’s a few years away, and I’m not very fast!)
I need details that don’t seem to show in most of the in-use, or in station photos.

Will gladly cover costs and postage for items of use!
