For a history of the company, jump over to my blog.

The Waterman company was bought by the Arrow company in 1917. Arrow continued to offer "Waterman" rowboat motors.
See Arrow for motors produced after the buy out.

For a full history refer to Arlan Carter's book, The American Rowboat Motor if you can find one!

The easiest way to tell you are looking at a 1912 Waterman is to look at the cylinder.

If it is facing rearward (NOT into the boat) then you have a 1912.

Interesting article by Cameron Waterman

This bracket was with a
Waterman Arrow #1032,
of which I have no photos.

To the right is a 1907 Waterman crank handle and period buzz box.
The clamp was for your boat...once attached to the boat's skeg (which most had back then) it was the receiver for a protuberance on the motor.

Skeg clamp

This protuberance fit into the skeg clamp .
