Troy, yeah, I looked that over before I posted since Maxwell had some good info. But he even said there was debate about it and I wanted to see what the consesus was about them and if anyone had anymore insight. Mine looks to be a circle and a slash. I originally thought it meant the axle was serviced too, but I'd say that was what the orange blop on the filler plug is for (white for non-sure grip). Someone posted on the DC forum about the suregrip getting the (X) and a non-sure grip getting a slash (/). Well mine is a sure grip and has a slash, the other 69 I had was a circle and an X and was an open 3.23. Crikey! Enough to make your head hurt. I'm just going to replicate and document what I see but it'd be nice to know what the heck it means.

Cheers
