toothed wheel - round or square?

[GAF2]

my g40 is a kreg 1992 and am trying to get a vernier pulley for it but am not sure if it is square teeth or round.  By looking i would have said square but the people who make the pulleys say round teeth are from 1991 to 1994 so am not sure here is a picture not very good mind you.
