What brand of motorcycle jacket was the original screen used Ceremonial Jacket?

I am super interested in seeing if I can track one of these jackets down. Does anyone here know what the actual brand was? I've heard it was a 1970's European racing jacket but other than that I can't find any more details on Google.

ALSO: I'm interested in any information on Han Solo's hooded jacket from Empire Strikes Back.

The Luke jacket has yet to be positively identified.

I'm sure you already know this but it's available thru lucas LTD..although im not sure who makes it??? What are your thoughts on this replica?
Good luck
