Founded in 1882, Portland Iron Works produced sawmill and transmission machinery in addition to drains, steam engines, and castings for machinery. During World War II, they manufactured one third of all throttle valves used on Liberty ships! This illustration is an original that would have been reproduced in a power transmission appliance catalog. Mild foxing, pinholes in corners present- see photos for condition.

Ready to frame, this original work on paper comes shrink wrapped with a foamcore sheet for protection. Bring an original piece of Portland history to your home or office!
