Couple of strange items

[andrewt]

First item appears to be a lock of some kind of lock with a pull handle

2nd is a small quarter sized item

Last is a flower with a square hole .... I have old doorknobs that use a square dowel and was wondering could this have been a doorknob backer

I actually know what the first item is Its an old icebox lock and a pretty one at that. I'm thinking you're right about the round object being a doorknob backer. Maybe the middle one could be a doorbell backer?

Here's mine I dug a few years back.

The two small objects remind me of old decorative brasses for furniture or trunks?
