38/7/1: Query of the Month -Bessemer Two-Stroke
Q: I have an engine I need some help with. It is a
Bessemer two-stroke throttled engine. It will run in both
directions, throttled from very slow to getting on with it pretty
I recently displayed it at a local hit-and-miss/tractor pull
show, and I was told about a gentleman at the show who has seen it
all, but when he looked at my engine with a confused look it really
made me wonder what I have.
My engine stands 23 inches tall. The base measures 11-1/2 by 11
inches and the dual flywheels are 16 inches across. It runs great
and blows beautiful smoke rings if you turn up the oil to it. I
would like to know what horsepower it is, what color it was and
especially what it was used for. Not being able to find one like it
at engine shows makes me wonder if it is rare or not worth having.
If it is rare I am wondering what kind of price value would be on
this engine. It is mounted on a skid holding the engine, gas tank
and a Model A coil. I think the cooling tank piped through the head
was added, because I was told that it was suppose to have a larger
skid-mounted tank with a screened cooling tower. Thanks for your
help. Tony Williams, P.O. Box 662, Angier, NC 27501.
A: Your engine appears to be a fairly early
Bessemer Gaso-Kero, most likely a 2 HP. These engines were built
from approximately 1913-1925, and were among the smallest engines
available from Bessemer Gas Engine Co., Grove City, Pa., best known
for their large oil field and industrial power units. We don’t
have any information on color, but it should have a skid-mounted
cooling tank, as you’ve been told.
38/7/2: Pincor Mower
I bought this Pincor power reel mower at an auction a few years
ago. I want to know where I can find points and a condenser for
this engine. It is a Model P-20, serial number 6782, Type 306519
built by Pioneer Gen-E-Motor Corporation, Chicago, Ill. The chassis
number of the mower is 6974. If anyone can let me know where to get
these parts, it would be most appreciated. Also, if anyone needs
information about Briggs & Stratton engines, perhaps I could
help. I have rebuilt Briggs engines for at least 35 years. Dieter

38/7/3: Sieverkropp Engines
On page 77 of the August 2002 GEM, middle column, fifth
ad down, there is a picture of a 1/2 HP Sieverkropp engine. I would
like to contact the person who owns this, but the phone number is
no longer in service.
I’m looking for any information on Sieverkropp Engine Co.,
Racine, Wis. There are three different engines shown in
Wendel’s American Gasoline Engines Since 1872, a 1/2
HP, a 1 HP and a 1-1/2 HP. Any information, including reprints,
would be greatly appreciated. Bob Hansen, E2510 Twin Lake Road,

38/7/4:Gray Marine and United
This is in response to 38/5/2C, the picture of an unidentified
The engine appears to be a Gray of 1906 to 1910 vintage, and it
could be anything from a 12 HP up to a 24 HP. There should be a
serial number on the hub of the flywheel. I have a 2-1/2 HP, serial
number 21907. I also have a number 36 Gray reverse gear, and
I’m looking for a number 40 Schebler Model D carburetor, timer
cap and water pump. I traded Model A parts for this engine, the
reverse gear and a Stover engine that was rusting away in a sawmill
in Bellville, Mich. The 1907 Gray marine has a big round muffler
and no water pump. What sizes were they made in? The Stover is a
two-cylinder, 6 HP, with the numbers GAP V5228555, and VF 2285.
What were they used for? Finally, I have a Falcon 25 four-cylinder
United States Motor, serial number 13728, and I’d like any
information about it, including color. The engine has a
transmission with it, and an aluminum front cover and pan. John
Plotz, 11299 Cardwell, Livonia, MI 48150.
38/7/5:Maynard and Sattley
I’m looking for information on a 1-1/2 HP Maynard, serial
number 16417, especially any literature and/or pictures of the
governor, ignition and the head setup. I’m also looking for the
same information for a 1-1/2 HP New Sattley, serial number 61328.

38/7/6: Stover Pump?
I have a deep well water pump. It says ‘Stover number
4-1/2’ on both of the connecting rods. It also has the
following numbers: ball gears show 472-P, upper cross head 476-P,
base of the pump 470-P, small gears 472-P, and brass packing nut
shows 474-P. My pump has two old-style, zerk-type grease fittings
on it. This pump has four holes to very the length of the pump
stroke. Was my pump made by Stover Engine Co.? What year was it
made? I painted the whole machine dark green. Douglas Poor, 12058

38/7/7: Wisconsin V-4
For some months now, I have been attempting restoration of a
circa 1954 Wisconsin V-4 air-cooled engine. It is a Model MVE4D,
serial number 2411578, specification number 115315. I have been
able to find a gasket set, rings and finally a set of rod bearing
inserts. I found a set of NOS pistons, but the problem is that this
is a military model, as indicated by the ‘M’ in the model
number. The pistons are different, as are the connecting rods, and
the crankshaft journals are larger. Does anyone have a military
model manual? I have a standard manual. Can anyone tell me where I
might find correct pistons? I need 3-inch diameter, 0.030-inch
oversize pistons. I hope to write a Gas Engine Magazine
article on the restoration when and if completed. Any help will be
greatly appreciated. Jim Davis, 21 Foresters Lane, Springfield, IL
62704-5312, (217) 546-4790.
I have a couple of Monitor engines and would like to know their
year of manufacture. The first is a 3 HP, Type HJ, serial number
7077, and the second is a 1-1/4 HP, Type VJ, serial number 15329.
Also, 1 have a set of flywheels with governor weights, crankshaft,
connecting rod and piston. The flywheels have a casting mark of AC2
and measure 18 inches. Casting marks on the governor weights are AB
12 and the crankshaft is stamped C1845C on both ends with an AC
just above the keyway, but all the Cs are backwards. Any help would
be appreciated. Richard L. Robertson, 72339 250th St., Graceville,
