Mystery Engine

I found this in a junk pile.
The nameplate says "Lawrance Power",
Obviously four-cycle,
It's 24 inches wide, 28 inches OAL,
It carries a Stromberg NA-H1E carburetor,
2 Bendix/Scintilla magnetos (two plugs/cylinder),
It has a tachometer drive and an oil pressure line,
And what appears to be an electric fuel pump, mounted underneath, just in front of the exhaust manifold.
It weighs around 85 pounds.
It has a mechanical governor connected to the throttle linkage.

Can anyone identify it?

Cool little motor!

 

Did a quick search... Scroll down...

Lawrance A-3?

Taken over by Wright.

 

A Lawrence L-3 powered the beautiful little Sperry Messenger in the early 20's.

 

Thanks for the interesting replies.

My friend sent me this link. https://commons.erau.edu/cgi/viewcontent.cgi?article=1224&context=jaaer

Halfway down the first column on page 7, there is a description of a model "N".
This may be my engine.
I plan to restore it cosmetically and donate it to a museum.

No, it's not.
Description: The model 'N' is 3 cylinders; read the whole paragraph in your article.

The model 'A' is 2 cylinders... see my post #3 above. It almost has to be the A-3....

Besides, they misspelled Lawrance.

 

Wrong, Mr Tcar.
Here is the wording: ''Lawrence build a 40 HP engine weighing 80 lbs.; this 2-cylinder engine was designated the Model ''N". This engine was then modified to meet Army requirements and now featured 3 cylinders in a radial arrangement, produced 65 HP, weighed 147 lbs., and provided a specific power rating of 2.3 lbs.!HP; it was designated the Model "L" in 1918".
