Floyd Rose Locking Nut, Made in Germany/Gotoh. For sale as junk.

Thank you for looking.
These items were found while organizing my tool box, or were stored because they didn't fit.
I have no memory of using them, so their operation has not been confirmed.
The nut caps are Gotoh brand, but they seem to be usable with the genuine ones as well.
This is a junk item starting at a low price, so please refrain from complaints or returns.
We look forward to hearing from those who can use these for repairs.
