John Deere Morco Rain Gauge & Recorder Pittsburgh Steelmark Runs Like a NOS Vtg

I can't date this specifically, but the original Morco insert has the Pittsburgh Steelmark, so I suspect this is circa 1960s/1970s. A little about the Pittsburgh steelmark Individual steel makers could use the design to promote the steel in finished products, and to help create a competitive awareness of the strength and quality of steel against aluminum and plastics.
