Buckle/suspender clip

[RustyRelic]

While I don't think these are CW relics, they were found near 1800s cabin spot that had troop activity in the area. Anyone know the date range for either? I've never seen a suspender clip like this one. Were there any CW buckles like this one or similar?

First pic looks like an ACW sling buckle
