Your engine is a Gray Marine Model " T".
They were mfgd about 1911 to 1920.
Engines were Gray's top of the line and most expensive two stoke
marine engs. They were a true Two / Three port design !
Had no oilers, mixing gas and oil was just discovered. They were available in
one, two and three cylinders.

Model T's used a Krice Carburetor, later engs show up with Scheblers.

If the drip oiler was original to the engine you probably have a 1911-12, by 1913 drip oilers were gone.
It's very possible that faintly etched in the face of the outer flywheel rim is a serial number ( hard to find especially under a coat of paint ) if you can find it post back here and I can date the engine !

Harry, on your Gray marine engine article the catalog engine photo is a Model
"R" it was first marketed by Gray in 1908, you can see that the engine is two castings- the cylinder flange bolted to the upper crankcase.

Your engine that shows the rebuilding is the very first Marine engine that Gray designed and manufactured, it was a single casting cylinder and upper crankcase one piece.
This engine was sold by Gray only in the year 1907, and never given a model number only marketed as a 1907. There are a very few of these around compared to the later Gray marine Two strokes.

This is a 1907 Gray Co. illustration and information, you may copy as use it if you choose to !
