Miscellaneous: Things We Need Words For

Things we need words for: A small machined metal or molded plastic part separated from its intended application carefully preserved in the (usually) vain hope that someday it will become apparent what it was made for and where it belongs. These things are clearly important and probably irreplaceable but not where they ought to be. The sort of little bit that, if you have it, the thing it goes to is ten times more valuable than an example of that thing missing the little bit you can't figure out.
