I did look at some vintage CHP jackets and while they were made of thick leather (2.5-3oz) .. .they were generally steer ( I only ever saw a few horsehide examples and the hide was always significantly thinner ( max 2.5oz) than CXL and while it looked chrome tanned it didn't have the same "hand" as 20-30 year old Horween CXL ( this is the oldest Horween I could find for comparison). In general there were no labels / madrkings to identify the original tannery either.
I have looked as some extremely thick leather motorcycle jackets but mostly from the 60's and 70's. I've studied Rin's books and various other publications .... spoken to most latter day manufacturers who can still be found and who still have corporate memory that far back ..... and the general view is that the fashion was simply not to wear really thick leather.
Look at the materials which made up the A-2's, the early bike jackets and also the early fashion jackets and it was predomiantely thinner hides which draped beautifully ... look at the Hartmann and Luftwaffe jackets, the French M/C jackets even the early (30's and 40's) US M/C jackets ..... even the "tough" work jackets were still not on a par with 3-3.5oz CXL steer or horse of today. It's beautiful leather but I still come to the conclusion that it is an "industrial" product which "we" have re-invented as a GREAT jacket product ... but it is by no means either "original" nor was it common.
As I said .. I've yet to see a golden era jacket in anything like as thick leather !
