HO scale horizontal boiler for the "Little Pine" Backwoods Sawmill. These types of boilers were often from scrapped locomotives, or built specificially to power lineside industries. Very common in Logging and Mining Operations until about 1930.
Smokestack is not included, to allow for infinite options. A piece of 5/32" K&S brass tubing fits perfectly, allowing the modeler to cut a stack to their desired height.
