Smith & Winchester: A well-documented Boston firm (established around 1880) that supplied steam, water, gas, and plumbing equipment, including boilers, pumps, and expansion tanks. Their 1894 illustrated catalog highlights riveted steel pressure vessels like this one, marketed for residential and commercial heating installations. They acted as distributors and specifiers, often commissioning custom or semi-custom items from local fabricators like Wendell for their clients. The catalog includes sections on "Steam-Heating Equipment" with similar riveted tanks featuring sight glasses and brass valves, emphasizing durability for high-pressure hydronic systems.
Wendell St. addresses appear in Boston city directories as manufacturing sites from ~1885 onward, with peak activity in the 1890s–1900s. Smith & Winchester's catalogs date to at least 1894, and their product lines align with this era's standards for ASME-unrated (non-code) pressure vessels.
