OK,OK, now I am truly confused (Again) I thought in the 60's it was safe to date 'em by the 1st # in the series.That would make that kmag a '61 (I am not questioning B.D.'s or anyone else's answer)reason I ask, I have one that must of come out of the form that same week, 4lbs lighter, last 2 digit different is all and I thought it was a '61 and does that mean my Polar is not a '63 it starts with a 3 but now I have no idea what year it is. dang it.
