If you cant make out the numbers, from left to right they are: 213312
Also, if you notice on the first one, the hole is bigger than the others. It seems like it was cut or something. The locking nut that holds the string slips right through and falls out the bottom if I put it in. Obviously with string on and everything tightened it won't, but is it anything to worry about?
EDIT: I noticed that the heights are a little different. 3 Being tallest, 1 shortest. Why is this necessary and why would they be set in that specific order?
