On page 33 of the Sept-Oct. 1967 GEM, is that long, informative story, 'Information on Gas Engines', by Virgil Gerdes, Route 4, Morrison, Illinois 61270. I would like to comment on several parts of his story, favorably, but I am pressed for time now.

In the last paragraph of Virgil Gerdes letter, found on page 36 of the above issue, is his question as to what type his early Fairbanks-Morse 4 Hp. engine is. The first engine he describes is undoubtedly, the horizontal, hopper-cooled engine. I would say these engines, in 2, 4 and 6 Hp. sizes were put on the market around 1908 and 1909. At first, they (F-M Co.) did not advertise any type. I must include, also, the 1 Hp. 'Jack Junior', a horizontal hopper-cooled engine, which I believe the F-M Co. brought and put on the market, along with the 2-4 and 6 Hp. hopper-cools, about the same time and gave it no type number or letter either. Then, around 1909-10, the F-M Co. designated these engines as the type 'H', including the little 1 Hp. 'Jack Junior', which is quite differently designed than the larger 2, 4 and 6 Hp. sizes. At the same time the larger horizontal engines, sizes 5 Hp. up to 60 Hp. were designated the type 'N' engines. The 5 Hp. and the 8 Hp. sizes could be furnished either as hopper-cooled, or with the closed-jacket, or tank-cooled type. In 10 Hp. and up, they were all tank-cooled. At the time Virgil's 4 Hp. engine was sold, it was probably advertised as the 'Jack of All Trades' engine. Now, Virgil's second engine, a 2 Hp. patented 1899, may have to be a vertical engine, as the verticals were the early engines built by F-M Co. They were, at first, called the 'Jack of All Trades' engines, made in 2, 3, 4, 6, 9 and 12 Hp. sizes. About the same time, around 1909-10, the vertical engines were designated the type 'T'. Since Virgil didn't state whether his engines in question, were horizontal or vertical, leaves me a little helpless. The 2 Hp. hopper-cools, were not built as early as 1899, as I get it. Might add, none of the Fairbanks-Morse engines were type 'M'. Any comments to this letter, please mail in to Anna Mae for publication.
