Not sure about serial numbers, but the easy way to tell is if your crank pulley has 8 slots or 4. If it has 4, you have a short nose crank.

Well after i removed the pulley i wouldve said i got another shortnose.. but according to the link and you guys i got a bignose cus its got 8 slots in the pulley... even the bignose looks pretty stubby....

Found it! I couldn't remember where I read this. Good info.
