<VV> Camshaft question

[Jim Houston]

Just disassembled the 140 I picked up recently, and the cam doesn't have 
any markings where the Junkyard Primer shows the part number.  All the 
markings are as follows:  Between the last two lobes opposite the gear - 
K71 ;  the next space has "CWC" ; then the next one is "C1" (or CI); 
then "D1" (or DI); and finally, near the gear "I6" (or 16).  Anybody 
have a clue about what this cam might be??
