Need help from Ping experts re Ping Eye 2

[Qwiklap]

Hello - thinking of buying this L wedge and a matching SW.

 

Trying to determine if this is a model that has “U-shaped” grooves. The writing is in the right direction (rightside up when in the bag) - but it only says “â€Karsten”†not “â€Karsten Mfgâ€.”

 

Are these markings correct?

 

Thanks in advance

Here is the info that has been posted before:

• "V" groove models manufactured from 1982 through Summer 1984, identified by PAT. PENDING in cavity and KARSTEN MFG CORP PHOENIX AZ 85068 U.S.A. upside-down on back of top rail.
  
• Eye2 Lite models introduced in 1984, identified by PAT. PENDING in cavity and KARSTEN PHOENIX AZ 85068 U.S.A. right-side-up on back of top rail.
  
• "U" groove models manufactured from Fall 1984 to Fall 1985, identified by U.S. PAT. D276644 OTHERS PEND. in cavity.
  
• Radiused "U" groove models manufactured from Fall 1985 to March, 1990, identified by U.S. PAT. D276644 and 4.512.577 in cavity.
  
• Modified "U" groove models manufactured after April, 1990 identifed by dot beneath patent numbers in cavity.
  
• "New EYE2" models with reshaped soles, increased perimeter weighting, less bounce in wedges, and stronger lofts than the original EYE2 were first introduced in November of 1989. Identified by U.S. Pat. 4.512.577 and 4.621.813 in cavity, club heads produced before March 31, 1990 had no "+" in the cavity.
  
• In April of 1990, a "+" was added to the cavity, and this model became the EYE2+.
  

I believe the version with "Others Pend." is the one that spun the ball the most. If you ever see the face of one of these wedges, the grooves look much wider than subsequent versions.

 

Some of the old Ping wedges for sale look like they've been dragged down a gravel road (likely from a lot of bunker shots or hitting sandy range balls). Even if the face looks clean, often times the grooves are still worn down quite a bit and the performance isn't great (I have a lot of old Ping wedges lying around and they all look fine, but I'm pretty sure the grooves are quite worn on some of them based on how the ball reacts at times).

 

If you want to get a set because these wedges are "cool," I'd say that's fine. However, if you think they are going to work better than anything new you may be disappointed.

Huge help - thank you. I had one of these before, and just thought it might be cool to check out.
