Brad says ~
This is my 4 hp. Gray engine. I got it in 1999.
I have ran this one a few times. It just does not seem to
run that good, maybe some day I will get it to run better.
I do not see a serial number at the top part of the head,
(but the number is a little closer to the water hopper on my
other 4 hp. Gray.) I will send more information and more
pictures of my engines when I can.

4HP model G, Serial Number 4G2259,
Photo shown when
the engine was originally installed in a woodworking shop in 1914.

This is a picture of my 2 1/2 or 2.5 hp. Termaat and Monahan Co.
engine. Made in Oshkosh, Wisconsin. It still has the original paint.
I got this engine in 2001. It came from Ohio. When I take it to shows
I get a lot of compliments. It runs as good as it looks.

This is my 12 hp GRAY, serial number 12-1047.
I saw some numbers on the end of the crank shaft. I think they
might be the serial number. It has a 12 then under that is has 1047.
I think the 12 might be the horsepower of the engine and the 1047
is the serial number.
I got it in 2003. I ran this engine
on Jun. 20, 2009 or someday around this date. I have ran
this engine off and on since 2003. It runs at about 110 RPM's,
and it fires one time every 11 to 14 seconds. I really like the
sound that this engine makes. A big powerful sound, and when it
fires or hits. The bore is 8 inches in dia. and the stoke is 11 inches.
I will send more info. about this engine, and more pic.'s.
