Carl Kunkel GRAY engine

Carl Kunkel's 4 & 9 hp GRAYs

Carl says ~

I HAVE A 9 HP GRAY ENGINE, WHICH HAS A CASTING # 94H29
ON THE WATER TANK. I CAN'T FIND THE SERIAL NUMBER ON IT.
THE TANK COVERS THE TOP OF THE HEAD WHERE THE NUMBER
IS ON MY 4HP. DO YOU KNOW WHERE THE NUMBER IS ON A 9HP?


UPDATE:
WHILE LOOKING ON THE EDGE OF THE FLYWHEELS, I THINK I
FOUND THE SERIAL NUMBER. ON THE GEAR SIDE, THE NUMBER
4.1019.9 IS STAMPED ON THE END OF THE CRANKSHAFT. THAT
STYLE OF NUMBERS IS THE SAME AS SOME OF THE OTHERS IN
YOUR LISTING.

ALSO, MY 9HP LOOKS JUST LIKE

HARRY COOPER'S 12HP.

IT EVEN HAS THE CASTING NUMBER "9-12 4H52" ON THE BLOCK
WHERE HIS IS. THE BLOCK ON MINE COULD BE FITTED WITH A
LARGER CYLINDER TO MAKE IT 12HP WITH A POSSIBLE
CRANKSHAFT CHANGE.

THANKS AGAIN, CARL
