If you have a Standard Talking Machine victrola then this is for you. Standard Talking Machine came out with the gimmick that they would use a 1/2" spindle while everybody else had a 1/4" spindle. The marketing behind it was that if you purchased their machine you would have to purchase their records. Needless to say, it didn't work. I have a Standard Talking Machine but I had the spindle turned down.
