But not *all* 140s.   Later PG variants had cranks that weren't nitrided.
 Got a couple, no ampersand symbol on the crank.    I wouldn't sweat it...  

Either way, a 140 can use any late crank and be just fine with it.  The
nitriding won't substantially increase the cranks strength at all; more for
keeping the crank from getting scratched by garbage in the oil.   Keep the
oil changed and you need not worry about not having a hardened crank.
