That school looks a lot like the same one that's been in videos for decades now (Jeremy Klein has tons of stuff over that hip, among many others).
If it's that one, I've been trying to track it down for many years, and the best info I have is that it's Gardena school at the corner of Vermont and Redondo Beach Blvd, but I haven't actually been there to verify.
I got a bit obsessed locating all the LA schools with hips and bank-to-bench spots about 10 years ago, and this is the one I never did find. But I've been to pretty much all the others (Lockwood, 7th st., Venice high, Kenter, Paul Revere, Los Feliz Elementary) and this is definitely NOT any of those, so... FWIW.
