Default Need more information on this odd Ottawa engine

Hello group. Hope someone can shed a little light on this fairly Ottawa Log Saw motor I picked up over the weekend? If you look at the picture you will notice two things that sets it apart from all other Ottawa engines I've found online; It has a very large opening in the top of the water tank and the oiler goes through the water tank. The tag says "Ottawa Log Saw" with the number BS306 stamped into it. It is missing the magneto, gas tank and mixer. I can fabricate the gas tank but looking to buy the mag and mixer if anyone has one for sale.

Can anyone tell me roughly how old this engine is and what the horsepower rating might be? I can't find anything online for this motor.

Thank you in advance!

These engines were used on a log saw mounted on a Y shaped frame with one wheel. I think they rated them 2 hp. Rotary mag will be hard to find. One of the latest styles of engine Ottawa made.
