AHHHH It's a 1123-1, mostly referred to as a Spurlock (although MOST ludwig hi-hat stands back then HAD the spurlock feature).

Yeah, it's NOT a flatbase.

They later dropped the "-1" from the model number, just to ADD to the confusion.

Last question. What is it worth and would it be period correct for a 1964 set?

Not EXACTLY period correct, but not off by too much to worry about.

I JUST bought a damaged one of eBay for $19.00 USD. But in good shape they might go for $40 to $100.

Here's the 1964 stands that were available.

Thanks Viper. You really helped on this one.
