🔎 UNIDENTIFIED Unidentified brass

[jjjwada73]

This piece has a patent date of March 20, 1888 stamped into it. A friend thinks it has something to do with insulting wires on an old electric fence. Found in a now park, which used to be an 1880s-1940s farmstead. Could it be off an old telephone? Thanks in advance for your help.

It is off of a vintage roll-up window blind.

I know it's not a Camaro shock mount.
Maybe it's part of a horse drawn wagon?
