I now have the whole ROK group via inheritance. ROK has been consistently spectacular. Have Collins separately too, but a mediocre investment. Some doggy Arvin Meritor came out of that, I believe. The few shares of Boeing I got have been good.
Also recently inherited a ton of Bell Children dating back before the 1984 breakup. Today that amounts to about three or four so-so stocks and 20+ slivers of junk. Spinoffs and even recombinations. Several are defunct.
