Still got one. Good club.
There were two types. One had a removable baseplate that allowed you to change the weights. Advanced for its day.
I have the solid aluminium headed one with a red inset.
I believe Nick Price used one to good effect in winning the 1994 Open at Turnberry.
Check out the video at about 33 secs (you can't see the putter too well but the result is impressive!).
