WW1 Aero magazine Issue 175 (Feb 2002) published information supplied by the Massachusetts Aviation Historical Society about this vintage aeroplane. It was built by the Pigeon Hollow Spar Company of East Boston (founded circa 1830) for Reginald DeNoyes Thomas of Waltham, a WW1 Naval aviator. The Pigeon family operated the business until 1979 and Roy and Guy Pigeon were the principals at the time that this and other aeroplanes were built by the PHSC. They supplied light weight,but strong spars and masts for ship and yacht builders in the U.S. and the U.K. In the period after 1910 they built aeroplane fuselages, wings and seaplane hulls for a number of manufacturers as well as control cars for USN blimps.
I think the Boston and Waltham referred to are the US ones, not Lincs. or Essex !
