That Mocom 70 is from the mid to late 60's.
Here are a few links to police radios that are more era correct for the 1949 panel.

Most public service agencies these days are switching to the Apco-25 Digital system & a good number are on 800 MHz. "trunked" systems which are tricky for the novice to monitor. Some jurisdictions even use encryped transmissions that are virtually impossible to monitor.
