Vintage calibres hand hole sizes

Does anybody have a list of the common vintage calibres and their corresponding hand hole sizes?

I've come into some hands and started the research but it is a laborious process...

I don't know how accurate they are but I suspect a bit better than anything except Omega themselves.
