Both of these were from a colonial site. Not sure what they are. Maybe one of y'all know. The square looking thing is pewter.

Last item looks like hinge from a scale/engineering ruler. Here is a similar one.

Now there is an idea. Even if its not off of one of those. it does look like it could be a hinge of something similar. Thanks!
