Some kinda strange horse tack?

Any ideas on this its the first iv ever seen it.

wild guess.... adjustable sturrip holder for saddle

Albert,  did you find it next to the corrals there on the hill?

NOPE! found another homestead on the hill, got 2 service buttons and 3 wheats, still a couple more places that look pretty good to the north.  I got a few keeper relics but nothing spectacular.

  Theres way more to that hill than meets the eye.
 Nvere seen this type of tack B-4

I'm going to take a stab here but that looks like the piece that goes on the back of a saddle that holds the saddle bags in place.  

This is on a military saddle but you get the idea.

It could be a piece off of a McClellan saddle.

Looks more like a spur attachment for the leather instep strap.

I looked at my McClellan saddle tonight and found that the fitting is similar except the saddle fitting does not have the loop...the McClelland fitting is afixed with 2 wood screws about 1/2 inch apart
