Featured Baby jumpsuit - 1920s

That's what I thought too.
However, it looks more like a screwdriver end. Maybe it's been squashed.

 

I suspect #1 is a pocket watch key. It has a swivel mount and all. It seems more copper than gold. #2 is brass. Both 1 and 2 have holes in the end. #3 does not, and it doesn't look squashed. I would guess it to be a clock key, hole or not.

No furniture from that source. I do have dresser with drawers that would lock if there was a key, but none of these fit.
