Mr. Mott actively collected windmills after his retirement from Ontario Hydro in the mid 1970s. Before that he acquired windmills as he came across them in the course of his lineman duties in south central and southwestern Ontario. Whitman Brothers is an excellent example of the smaller end of the Canadian windmill manufacturing industry that had to rely on close relations with the local community for its sales base. Although these firms existed across much of the rest of Ontario for some reason there was an inordinate number in small communities across southwestern Ontario. For example the "Pepper" windmill a contemporary of the Whitman was manufactured in Forest, Ontario a community not that far from its home in Ridgetown. Due to its rarity Mr. Mott did not feel comfortable mounting the Whitman to a tower/derrick for display/operation in his yard. From original Whitman advertising material he was able to copy and from extant examples he was able to examine in farmer's yards Mr. Mott determined the Whitman derrick was one of the earliest in Canada to be made of galvanized metal. This windmill is in very good original condition.
Function
Part of a windmill/ All parts to this catalogue number form a windmill.
Technical
This windmill is referred to as a "back geared open" model. This meant the gearing sat just behind the central pivot point of the top of the tower and that the mechanism was open to the weather. This meant that although it was easy to monitor its operation from the ground, it was necessary to climb the tower to grease or otherwise maintain the mechanism. This style of windmill was most commonly manufactured prior to 1900.
