I couldn't find these markers in Tim Rohr's thread on gallon markers, so I'm hoping somebody has an idea what pump they might be from. I got the cylinder with only the top, base and markers in Eastern Washington last year with no history.
Guessing they could be Canadian as it took a metric wrench to get the top inspection plate off. The markers measure 2" wide by 1 5/8" tall.
