Mysteries Continued

The mystery continues regarding our APLCO engine, but some new
information has come to light. Dan Dorece, contributor to Gas
Engine Magazine, says the engine was either made by Termaat &
Monahan or Gray because at one point the two companies made engines
for each other. Or perhaps T&M made engines for Gray after a
fire in the Gray factory in 1916? There are many stories floating
around, but photos speak louder than words. The similarities
between T&M and Gray and our APLCO engine are unquestionable.
At the right is a photo of a T&M 1-1/2 HP engine from the back
cover of our March 1997 issue. Despite obvious similarities – and
differences for that matter – the real story is in the numbers. On
the side of the T&M engine, under the logo, is: 14H29. Notice
then on the APLCO engine: 14H29. Some Gray engines also had a 29 on
the side of their engines. Thomas Green has a website about Gray
engines and says these numbers mean 1 HP 4-cycle and the H29 would
be the serial number. This doesn’t totally add up since more than
one engine we have seen has 14H29, but it could be a good start as
to the meaning of the numbers.

Michael Miller writes: I also have in my possession one of the
APLCO engines described on page 11 of the May 2006 issue. I
purchased this engine near Pittsburgh, Pa., more than 25 years ago.
It is in excellent condition and we know nothing about who built

If you look at page 9 of the January 1995 GEM, you will see an
identical engine, only it has the name OshKosh cast in the sides of
the hopper.
