This was given to me as it is. The slave pedal appears to be functioning fine I have just never used it attached to the beater pedal before. The main pedal works and I was using it as a single. I have no connecting rod or extra beater for this. These were very dirty when I received them and I tried my best to clean the dust off. The spring is also beginning to feel weak and will need upgraded, but pedal can still be used like it is.
