What is this? Can anyone identify this artifact?

[Story]

Had the same idea, but thought maybe the opposite end - the top - with the hole being for a fixing screw or nail, or maybe to hold a decorative tail.

The hole expanding from rust over the ages.

it could be a pin of some sorts to hold something in place

Reminds me of a tent rope tensioner?
