Model

This is a model steam engine. It consists of a metal pump and a boiler box on a plywood base. The pump has a green body, a red wheel, and some wood veneer. The boiler box is brass, with a black circle on either end and a gauge at the front. The gauge goes from 0-30 in increments of 5. It says "JOHNSON SERVICE COMPANY / MILWAUKEE MASS / AIR / Jas. P. Marsh / Corporation / ___ MADE IN USA" on the face. There are three pipes coming from the top of the boiler. The wooden base has been stained a dark colour. There are four bolts coming out the bottom of the base. There are several other holes in the base from previous bolts. "PHSM" has been written on the edge of the base in white ink.
