Had the pleasure to update a little bit of a sprinkler system that is almost 100 years old. This system back then was top of the line. Has two zones one for front yard and one for the back yard. Each zone had a 1.5" globe valve controlling flow. Out in the "field" zones were all copper and reduced to .5" This sprinkler is most likely from the 1930's, National Muellermist company. The cool thing about this sprinkler is it still works, but will be retired!
