The above actual size of a partial nameplate (shaded area is
missing) is from a small 2 cylinder inboard marine engine I have.
Could anyone fill in the missing letters or might you have a
nameplate not in use? There is a 9′ x 6′ cast-iron exhaust
and water manifold on side of engine. Also would like to know year
of manufacture and horsepower.

Has anyone heard of a book titled, ‘Men and Volts?’ All
letters answered and your stamp returned.

These photos are of a Monitor single cylinder engine that we
own. It has external valve lifters. It apparently is started by
flywheel handle. The engine is broken internally. It is cooled by
water poured into the top cavity.

If you can help us identify origin, date of manufacture or parts
availability we would certainly appreciate it. We would like to get
some information before tearing into it.

I have subscribed to your magazine since 1966 when it was first
printed. I have every issue and I enjoy the magazine very much. I
refer back to some of the old issues quite often for help and
details while working on my engines.

Now I am asking for help. I am enclosing a picture of an engine
I got this summer. It was built by the Aermotor Company, Chicago,
Illinois. 4 1/8′ bore x 6′ stroke, 27 inch flywheels. It
has a round bowl shaped hopper and the cylinder is a sleeve pressed
through the lower part of the hopper casting. Battery ignition with
the igniter in the center of the cylinder head. Hit and miss
governed. The cam end of the push rod is supported on an arm that
swings as the rod moves back and forth. The skids are 2×12 planks
about 4? ft. long (and one end has been sawed off) set on a slant.
The paint was originally red with yellow striping on the

I would appreciate information from anyone as to the approximate
date of manufacture, shape and location of the gas tank, battery
box and any other data.
