Pennsylvania State Police Insignia

State Police Museum was selling these yesterday. Not military but I still liked them. The Keystone is a Hat badge. Not sure of the date but similar it seems anywhere from the 30's to the 60's.

The small ones are collar disks from about the same period. The 2C means these were from the Hollidaysburg PA Barracks. The 107 is the officer's number. These are also screw posts but the post does not go all the way through the base.
