Pre-eb sabres and stingrays, how many exist?

I read that at peak production they made 1000 per month in 79, and that’s all instruments, any numbers out there exist in how many of each model by chance? I’d imagine in that case, in regards to sabres, that maybe only 2500 or 3000 exist with the 7.5 radius neck! That doesn’t seem right though! I’d imagine they’d be super valuable if there was only that few in the world!
