I don't think the number on that tag is a serial number. The bluebook I have lists the 176 serial numbers as 539009-809698. Not sure if the serial number was on another tag on those or not. The oval tag like yours pictured was half gone on mine but the rectangular Underwriters Laboratory tag was on it and there is a six digit No. on it that starts with 643... Maybe that is the serial number? It would fall in the range above. My pump looks just like yours, a single cylinder. The date of manufacture of the 176 is 6-20-31 - 12-16-38 inclusive according to the blubook. That's it for the info I have....GB
