Both of these engines have William Galloway, Waterloo, Iowa brass tags on them.
The air-cooled has serial no. B1311 stamped on the end of the crankshaft. The water-cooled engine has serial no. 0110.
Several of the parts are identical on both. It appears both engines were sold by the William Galloway Co., Waterloo, Iowa.
Can anyone tell me where these engines were actually built? The air-cooled looks like the one built by Bluffton Co., on page 60 in C.H. Wendel's book. Any information would be greatly appreciated. Al Shipp, 2912 Asherton Ave., Nashua, IA 50658.
