Whatnot ~ watnot "Is that what it is called?"

3. a stand with shelves used for keeping or displaying small objects

~ Canadian Oxford Dictionary

With generations, come word changes.  The whatnot is one of those words.  The American Oxford Thesaurus perhaps has the only relevant word:  what-d'you-call-it, or whatchamacalitit ~! (a contraption; gadget; gimmick; thing or instrument.)
