Yes, I agree with Mike. That's what is called a 70s stamp, and the lathing fits that time as well. Did you buy a pair of hats? Or just the one?
Once the model ink is gone, weighing both the top and bottom is the next port of call for seeing if a pair of hats fits the New Beat weight ratio. I'm working up a history of New Beats and as part of that I've collected up weights. I've got about 40 pairs of weights so far, from different eras. I can tell you the grand average is
top 884g
bottom 1250g
and thus an average top to bottom ratio of 71%. So what are yours? If you tell us, I can make comment on whether they pass the weight test as likely or not. Nothing definitive of course. It's still early days in terms of evidence gathering.
Of course, if it is just a single hat then if it weighs in as a heavy one (1150g and up) then it could either be the bottom hat of a New Beat, or perhaps a marching cymbal. And that you cannot know if you only have the one and no ink. If it is lighter (like a New Beat top) at less than say 1000g, then we cannot know whether it started out life as a New Beat pair, or is just a hi hat from that time. The weights are in the same range for a top hat from a non New Beat pair or the top hat from an ordinary pair.
In addition to all the weights, I'm documenting all the different styles of model ink which have been used over the decades. I haven't got it all finished in HTML yet so the history and weights aren't yet up on my web site. But they will get there pretty soon.
The New Beat ink you are looking for may well be just on the underside of the bottom hat and not on the top at all. That's how they started out from 1963 onwards, and this ink style lasted well into the 70s:

Both word ordering, straight vs curved label, and location of model labels changed over the decades. But knowing they changed and knowing which year they changed in are two different things.
