Timing of Allis Chalmers B

[shadow350]

I am in the process of rebuilding the engine on my Allis Chalmers B. After I took the crankshaft and the camshaft out to have my local NAPA shop clean the block I realized the crankshaft did not have a timing mark stamped on the gear.

Does anyone know how to find the correct location of the mark? For example counting the teeth from the key way.
Any thoughts on this would be most appreciated.
Thanks
Fred

Looking real quick, what I've read, it is a straight line, not a round punch mark on the crank gear. Early model's had a straight line on the cam gear, later/newer models have an oval mark on the cam gear.
