I like the sound of that one Chromeo. The closest sounding cymbal I've got is an 18" which is a little heavier at 1240g. Mine is 1960s and has the 1.5" version of the trademark and the special cup (see below). I think yours would make a great crash or a very washy ride.
If you are up for a little more measuring I'd be interested to know which bell yours has. Any units will do, I can convert. Cool1
There are two likely bell dies used on your 18" cymbal: the medium cup and the special cup. The medium cup is about 5" in diameter, and the special cup is a little larger in diameter (5.5") and a little taller (3mm or so). In this first picture I thought yours looked like the medium cup, but in the video I'm not so sure. It might be the special cup.
Measuring the diameter of the bell can be tricky not because we can't use rulers, but because when the transition between the bow and bell is very smooth it is hard to be sure where it stats. I've described some of my methods here

And here's the thing about the difference in cup size. By the 1960s the special cup was used on the 18" crash and crash ride models, and the medium cup was used on rides. But I haven't traced the bell dies back into the 1950s yet. I've been collecting the info to do the study, but haven't processed it all yet. It's all part of tracking the different models back through time. Dedicated crashes didn't appear until until the late 40s early 50s according to Zildjian (Sound Lab White Paper #1 available via my site) but although they describe why dedicated crashes have larger bells, they don't say just when that came info fashion. So I'm looking carefully at bells from different production eras.
