Civil War Buckle Shield

Here are some finds from yesterday that I made in a farm field where an old house used to stand. I was particularly happy to find the Civil War-era buckle shield, a first for me. I also found a trigger guard. Any ideas as to what type of gun it may have been from?

Thanks for looking and happy hunting!

Nice finds, I was out once this spring for about 1/2 hr, table spoon, mixing spoon and a old door hinge added to my collection. Checked out your You Tube, enjoyed the videos, encourages me to get out more.

Some good digs there Tony. That trigger guard looks old!

Nice relics Tony. Any idea what the little art-deco looking thingy is?

I have no idea what the art deco thing might be. It is smooth on the back.
