One of those pipe lids... but ehhh... the item in question seems a bit larger than even a large "bowl" but ? ? ?
Anyway... this is a great mystery what is it. heh
Its got me guessing as well.
At first I thought this was definitely a parmesan cheese / crushed red pepper dispenser at first glance ... was certain of it until I saw the "side holes"... which defeats that theory completely.
