The 52 is the CG10 model black pearl with standard bounce and a DG wedge flex shaft. Looks about 1/2" short. This one has a few rust marks.
The 56 is the 588 TG (tour grind) model with a raw finish and tour issue DG shaft wedge flex.
The 60* is the BRZ 900 model low bounce with a DG wedge flex shaft.
Price drop to $50 shipped or trade.
I had a CG10 60° years ago and it was a great head. My wife got it a few years ago when I started playing something else and she left it somewhere, never to be found by us again.
How much play do these have on them?
They definitely are used but not abused. Grips are pretty worn. The grooves seem pretty darn good for their age. I updated the listing above. The CG10 appears to be about 1/2" short and the 56 is the tour issue model 588 TG.
Pictures can tell the story if you want to see some.
Lowest I can go... $45 shipped for 3 wedges!
