Three readers identified the "mystery" engine in the March/April 2005 issue of Steam Traction. The first response came from Paul E. Deo of Snover, Mich., who wrote:

"The mystery steam engine in the March/April 2005 Steam Traction is a Northwest, manufactured by the Northwest Thresher Co., Stillwater, Minn. They also built a return flue engine, which they sold under the New Giant name. I'm not sure of the manufacture date or the horsepower, but the flat spokes make it a later model and I'll guess it's about a 20 HP Keep up the good work on the magazine, I look forward to each issue. Also, I own a 1906 18 HP double Buffalo Pitts."

Right on Paul's heals was a letter from John Malsch, Pell Lake, Wis., who also correctly identified the engine as a Northwest, but thinks it's a 25 HP model. Regular contributor Alan New also correctly pegged the engine as a Northwest.

For getting his answer in first, by mail, Paul gets a free copy of Prof. P.F. Rose's Steam Engine Guide.

As ever, the first person to correctly identify the engine, by mail, gets a free copy of Prof. P.F. Rose's Steam Engine Guide. Good steaming.
