I have two original Bulls Eye putters and was interested in knowing more about them...
1st) On the bottom it has the Acushnet Bulls Eye stamp as well as '0 - SET 6 - S' and also stamped is
'Designed by John Reuter Jr.'
2nd) Again the Acushnet Bulls Eye stamp and '6 - A' as well as 'Heel Shafted Flange' this one also has a slit in the body and same shape as illustrated below.
I took these pics off the internet.
I think my Dad purchased them in the late 50s or early 60s?
