39/5/1: U.M.A. Engine Q. I have been trying to identify this engine's manufacturer. As I understand it, United Manufacturers did not make engines. The serial number on this engine is 5211. I am trying to determine the year it was made and anything else anyone might know. Gary Knorr, Old Salem Road, Springfield, IL 62707 (GKGKKNO@aol.com).
A: Your engine was manufactured by J. Thompson & Sons Manufacturing Co., Beloit, Wis. Page 513 of C.H. Wendel's American Gasoline Engines Since 1872 shows catalog cuts depicting the 'Thompson Tiger' line of engines. Further, page 3 of the May 1997 issue of GEM features catalog images of the Thompson line, including your engine, which is identified as a 2 HP model. The limited information available suggests your engine was current about 1912-1914. These engines were also sold by Lunt, Moss & Co., Boston, Mass., and possibly others.
39/5/2: Stewart Little Wonder I recently acquired this Stewart Little Wonder engine. I am missing the magneto cap and also whatever is connected to the little lever at the end of the governor shaft. Does anyone have a close-up of what should be there? I also need a clutch for a 2-1/4-inch shaft. Does anyone know where I could obtain one? Any other information would be greatly appreciated such as the year, horsepower, etc. Thanks. Don Leap, P.O. Box 703, Hyndman, PA 15545.
39/5/3: Unknown Tractor Does anyone know anything about this tractor? Is it a homemade machine? The only name on it is Jasper, which is cast in the rear housing. It has a Ford Model A engine and a belt pulley set-up. I'm planning on rebuilding the tractor, and I would appreciate any information about it. Thanks. John Fenske, 138 2nd Ave. S.E., New Brighton, MN 55112-7855; (651) 633-0129.
39/5/4: Cray Bros. Engine Enclosed are some pictures of a 1912 Cray Bros., Cleveland, Ohio, 2-1/2 HP engine. Manufactured by Caldwell-Hollowell Manufacturing Co., Waterloo, Iowa. An old friend of mine said he helped unload this engine from the train in 1912 and went with the owner by wagon to where it was set up in a blacksmith shop. I bought it about 30 years ago then had to sell it. Several months ago, I got the chance to buy it back. It is in very good condition, complete with the original clutch pulley and galvanized lid for the water hopper, but it is missing the crank guard.
I have never seen another one, and nobody in this part of the country I have talked to has ever seen one. I thought in the Midwest they might be more common as they were built in Waterloo. I would like to talk to anybody that has one of these engines or knows anything about them. I would also like to find a crank guard. Thank you. Harry W. Campbell, Box 241, Josephine, PA 15750; (724) 248-3913.
39/5/5: Sattley 5HP Q. I am restoring a Sattley 5 HP, serial no. 28344. Please tell me the date of manufacture and original color. I am told this engine was made by Field-Brundage for Montgomery Ward. Is this correct? Thanks for your help. V.T. Hunn, 5100 Dayton Road, Fort Worth, TX 76140-8042.
A: Unfortunately, we don't know of any serial number lists for Sattley engines. Field-Brundage did indeed produce engines for sale by Montgomery Ward, including a 5 HP model. As to color, early Sattley gasoline engines were black, kerosene engines were brown, and later Sattley's were a darkish green. An exact color match is pretty much impossible, and the best bet is to match the color of an existing engine.
39/5/6: Johnny-on-the-Spot I recently purchased a gas engine called 'Johnny-on-the-Spot' made by Gilson Manufacturing Co. Ltd., Guelph, Canada. This engine is serial no. 54833, is rated 1-3/4 HP and is a hit-and-miss.
I would like to know the year of the engine and the color code. Thank you. Joseph Powers, R.R. 3, Hastings, ONT, Canada K0L 1Y0.
39/5/7: Fairbanks-Morse Piston Rings A recent phone call from reader Clayton Millie got us wondering about something, and it's an issue Clayton would like opinions on. Namely, is there a consensus on retaining the protruding catches that are cast into the ring lands of some Fairbanks-Morse Z pistons, evidently to locate the piston rings?
Clayton says he's received conflicting opinions on the subject from both suppliers and restorers, with some saying you should file the nibs off and others saying you should retain them. Clayton is in the middle of restoring his 1917 3 HP Type Z, and he's trying to decide the best course of action. If you have an opinion on the matter, contact Clayton Millie at 1625 North C St., Fremont, NE 68025; (402) 721-1948. Drop us a line here, as well, so we can share in the discussion.
39/5/8: Stove Engine I have a Stover engine, Model KA, serial no. KA151765. The engine is pretty rusted up, and as far as I can tell it is missing the gas tank, cylinder oiler and the arm and bracket that opens the exhaust valve. I am interested in any blue prints, part lists and part suppliers related to this serial number Stover engine. I have the Power of the Past Volume Ill pamphlet with the operating instructions and small description of the KA-series motor. Kevin Boucher, P.O. Box 1353, Medical Lake, WA 99022.
