(Greenkeyer David Forbes told me this story just last night :-)

Oh I agree with you, it's a mixed bag of goodies. The problem in the
NorthStar engine example is that some lowly person rebuilding an antique
2004 Northstar won't have access to the intellectual property (IP)
needed to make 'em. 

And (more Greenkeys on-topic :-) after half a century, forget it. At
least you have a chance with old-stock lingering in an un-rusted state
somewhere, said chances increase when that 1930 bearing was made up into
the 1990's, that's a lot of old stock! With today's I.P. you won't have
a ghost of a chance, "physically" or legally. Maybe in 100 years design
and other data will settle down but right now you can't even read 1980
floppies, nevermind find the program the was written for or the machine
the program ran on.
