Wood Advertizing Thermometer Mac's Radiator Service

This is a advertising thermometer for Mac's Radiator Service in Lynwood, California. That is a suburb of Los Angeles in the eastern area near Long Beach. There is still company in the area but not the same location.
Based on the phone number with NEwmark I am going to guess 1950s for this. Plus or minus a decade I think. The "Calif" abbreviation was still used in the 1960s. It is a bit more graceful than the current CA.
This thermometer is about 14" long.
The metal thermometers are rather common. I do not recall seeing a wood one before.
