I don't know much about Cals, but I don't think it is a Block Bilt jacket.
I had a steerhide one by Block Bilt, photos here: https://www.thefedoralounge.com/threads/rare-block-bilt-1940s-chp-police-jacket.110722/
The teardrop Talon zip suggests 60s/70s, I think?
I have teardrops on this one (the first owner said he bought it from 'Star') however I always assumed it was a bit later. I suppose Officers part exchanged their old outgrown or ridden jackets.
