39/6/1: Case Airplane Tug My Case VAIW airplane tug has a mounted luggage conveyor. I wonder if this is shop-built, or is it a factory job? The front axle is 1 -foot longer on the heavy side and also has a transverse spring (like a Ford Model T). Other extras are a hand brake and the headlight. All these changes are neatly done, but an airport shop could surely have done them. Has anyone seen another one of these? Bruce D. West, 10684 Liss Road, Willis, MI 48191-9722.

39/6/2: Simplicity tractors Do you know anywhere I can get a book or information on Simplicity lawn tractors or walking tractors? Can't wait to get Gas Engine Magazine! I love to read about tractors and lawn mowers. William Faulkner, 3387 Grifton Hugo Road, Grifton, NC 28530-8319.

39/6/3: Watkins Engine Information Having recently become the owner of a Watkins engine, I thought I would pass along what information I have since at least two people have sent inquiries to GEM.

My engine is a 3 HP, serial no. 121. The engine has a full copper jacket for water-cooling, which is held in place by a steel band at the bottom of the jacket. The top has a cap-type nipple, which seals off, and the spark plug then screws into this.

The brass nameplate says: The Watkins Motor Co., Cincinnati, Ohio, No. 121, HP 3. It appears the exhaust would seal off the same as the top, although mine is missing this item. Also, my carburetor only has a large 'L' on one side and '3/4' on the other and appears a little different than Coulters as shown on page 8 of the March 2004 issue.

Hoping this information will help someone. This is my first correspondence on engines, although I personally have about 14 or 15 single-cylinder engines. I just can't seem to find time to play with them as I would like.
