This is a Company published book about the history of both the company and the innovative products that they made. It was published in 1960 and has photos of the 2 families that joined together to form the company. The company is still in business today, 2024, although now named Mestek, and still in Westfield, MA. This is a great slice of History book that describes how Central Heating became the norm for al buildings in the USA. This is a RARE find! Great gift for a History buff!!
