I have an older Scotty Big Sur Putter that has been copper plated.  it is a mid shaft putter that has a tip that measures .420 OD. This is a two piece shaft and the coupling in the middle has become loose.  The person that had this before be sent it off and it was repaired but that did not last long and has since been repaired for the third time. This also did not last so I cut that section our and made my own coupling. 

I wonder if anyone out there know where to get another shaft or what this shaft actually is?
