My favorite home made pairing is two 60s trademarked A Zildjian cymbals which are 732g over 1120g. That's at the lighter end of the New Beat range, but I like them. I sold two pairs of heavier ones before I came up with these. Like you I went looking for specific weights.
That trademark looks like the 60s short stamp to me.

I don't see it as being the 60s tall stamp unless it is 1.5" tall (versus about 1.25" for the short version).
The ink saying
Top Hi Hat
New Beat
came in at 1970. I had it as 1968 on my site, but it has since been moved to 1970 due to new information. Prior to 1970 Zildjian weren't marketing New Beats as a pair of hats. New Beat was just the heavier bottom you could order, so the ink on the top just said whatever the top designation was. I've got designations of Top Hi-Hat, and THIN although most have lost their ink. The earliest bottoms just said
New Beat
Hi Hat
because it was implicit it was a bottom since that was all that was offered until 1970.
The presence of what we call a 60s stamp on a cymbal which left the factory in 1970 or later isn't shocking. Given the information I've got it is easy to see that what we call the 1960s stamp was still in use in the first few of years of 1970. That's based on looking at the trademarks which are on specific cymbal types which came in at 1970-1972. The distinctive types are Flat Top Cymbals (1970 only) and Pang and Mini Cup Rides (1971). When these are found with 60s stamps that tells us the 60s stamp was still in use in 1970-1972 and we can spot those cymbal types without needing any model ink left in place.
