24/9/15 Oliver plow Q. I would like any information on an Oliver 23-A, two-way, hillside, walking plow. The seat adjusts to both sides so the operator always is sitting level. Also, the tongue adjusts from side to side, depending on which plow is on the ground. What is the proper color, and when were these plows built? John Bossier, 438 Maple St., O'Fallon, IL 62269.

24/9/16 Diaphragm Pump Q. See the adjacent photo of a Barnes 4-inch diaphragm pump. The engine, or what's left of it, is a Now, but I have no idea of its size, and whether gas or kerosene. Can anyone be of help so that I can begin the search for parts? McCabe Machinery, 4416 Walle Lake Rd., Hastings, MI 49058.

A. Without some dimensions to work from, it is hard to make a judgement. However, we recall a reprint of a Novo manual some time back, and perhaps it is still available from some of the GEM advertisers. This would give some of the dimensional data. Since diaphragm pumps exerted little pressure but gave lots of volume, they did not require much power-we suspect that 2 or 3 horsepower is sufficient.

24/9/17 Unidentified engine Q. Some years ago I acquired the engine shown in the photos, with the nameplate reading HP 5E, along with other serial number information. What make is this engine? Also I need to find a parts source for a Minneapolis-Moline Z tractor, s/n 00605965. What is the year built of a FBM engine, Z, Style D, No. 7521; IHC LA, s/n LAA48G46, and LB, s/n LBA120678, and a Reo Model 211, Type 6, s/n 3626 265? I'm 78 and have just started collecting engines. Ivan Mostoller, Route 2, Box 240, Deer River, MN 56636.

A. The engine in the photo is an Economy, sold by Sears-Roebuck and built by Hercules Engine Co., Evansville, Indiana. The M-M is a 951 model. There is an error on the FBM ZD number; the LAA engine was built in 1938, the LBA in 1947, and the Reo in 1951.

24/9/18 Before and After Dean Ailing, Box 10264, Burbank, CA 91510 sends along a pair of before-and-after photos of his Hercules 1? HP engine, and wishes to thank everyone who helped get the job done.
