Bally early 1960’s used lockdown bar. Has nickel slot on the left side in bar. Cast end caps have a lot of pitting. This is the style which has long threaded studs, and is held in place by a wing nut on each stud. NOTE: The picture shown illustrates that there is a dime and quarter slot. This bar has only a nickel slot on the left where the dime slot / plate would be.
