Figured ill beat the horse to death.

I wandered out to that parts '34 8 parts engine i have yesterday and looked at that crankshaft gear again. Only 1 '0' and again it looks like it was engraved with an electric pencil. I ran into the same years back on another PACKARD '8'.
Tried taking a photo but the '0' is so light NO STAMP that it dose not pick it up. No question that the photo from 32model901 shows 2 stamped '0's. SO WHY !!!!!!!!!!!! 1 vrs 2 ???????????? One thing that comes to mind is in a Service Letter they write about changing the Timing Chain. Maybe this is when they rev. the gear making???????????
MAYBE MAYBE MAYBE
And now we have a '33 gear without markings.

Ill c if i can find that Service Letter with the Chain write up.

"There is also a change in the type of timing chain used."
