Talk about rare.... LH Scottsdale putters qualify.  Not many were made. This lot consist of two such putters: a B69 and a Cushin.  The B69 is in near mint condition while the Cushion is well used. 

There is a small dent low in the shaft when viewing the back of the Cushin, plus the chrome on its "Z" shaft is worn on the bend. The Cushin's grip has been replaced with a newer Ping grip.  On the other hand, the B69 is in pristine condition. It shows little to no wear and still has its original grip and shaft bands.

In the image of the grips, the green portion of the shaft band on the B69 reads "Small Z".  Karsten devised three different Z bend shafts in January of 1968.  The different bends would provide his putters with differing amounts of toe hang, to accommodate different stroke styles, from straight back and thru to heavily arced. To learn more about the three different Z-bend shafts, see ATPWP p 109-110.
