I bought both the 18" ride and 22" ride new in 1965 at Manny's in NY.
I just always assumed they had the typical 60's stamp.
I happened to take a closer look at them at rehearsal the other night, and now am somewhat confused.
Through the contributions of members (esp. Drumaholic) I learned some time ago that the lack of "the 3 dots" indicated late 50's. Also the stamp is noticeably smaller that the one on my 18" crash purchased some years later. (It HAS the dots.)
Now, I know when I bought them (1965) and I know they were new at the time. So what gives? Could it be they sat in inventory that long?
(18" = 1535gr) (22" = 2820gr)
