These tank cooled engines were made in Milwaukee, Wisconsin, by
the Western Malleable & Grey Iron Manufacturing Company, before
they moved to Port Washington in 1909.
The small one is a 2? HP with a bore and stroke of 4? x 5 and
very heavy 20′ flywheels. This tag says, ‘The
Simplicity,’ no serial number or horsepower. A boss on the side
of the cylinder is stamped C 81.
The larger engine is on a Bettendorf truck and I believe it is a
10 HP. The tag on this one says, ‘The Simplicity Built By The
Western Malleable & Grey Iron Mfg. Co., Milwaukee, Wisconsin
USA,’ also with no horsepower or serial number. A boss on the
top of the base is stamped H405. It has a bore and stroke of 7? x
11 with 46′ flywheels.
Both engines are hit-n-miss with make-n-break ignition. I have
owned the 2? since 1971 and got the 10 in 1998. The 2? is a very
good running engine but I am still learning how to run the 10 HP at
I would like to find out more about the early Milwaukee-built
Simplicitys. I would like to know what the letter in front of the
number means. All I have seen have a letter and a number. Is it the
size, year, or what? I would like to start a roster of these
engines and with enough response the puzzle can be solved. All
those who respond will get a copy of the roster. Send serial number
This picture was taken at Jim Keats’ show near East Troy,
Wisconsin, October 10-11, 1998. This is the best little show
(getting bigger) in the Midwest. The show is built around Jim’s
large collection of rare and interesting engines. Enginemen came
from Illinois, Iowa, Minnesota and Wisconsin and brought some
engines rarely seen at other shows. This is the last show of the
year that I attend, and a good one.
