sorry to ask this here ..
but i have been looking for this information in my "history of
technology" books and on the web - but all the looking and googling
around was fruitless ..
aluminium extrusion - production of aluminium profiles, seamless pipes etc. ..
when was it invented ..? was it in actual use before or during ww2?
