same here Bill, thru the years I would pick up what we called "whatsit's" where none of us could come up with a reason for its being.
it is good mind exercise. I have had items that took a long time to ID, did not tag it, a year or two later would find it in the garage
or shed, stare at it and lo and behold, "what was that for" and to this day, I still do not tag anything.
