Looks like "C" pillar trim piece for a Ford or Mercury from the 60's, possibly a 1964 4 door hardtop of one or the other.
Doesn't look Ford, but did Mercury parts have the Ford logo on them even if they weren't interchangeable?

Weed, don't be too hard on yourself, it's like One piece of a jigsaw puzzle. The Aha moment comes when you find it's rightful place. Don, no worries, we are with you! Is a Ford piece, just have to find out which one. The hunt is on.
BINGO!! I remember disassembling one of those many years ago. If anybody needs it, it's yours for the price of shipping.
