Does anyone know when the Wayne 80 pumps changed from the "clock" type calculator face to the rectangular type calculator faced plate?

Thanks.

I'm guessing you mean from the "8 Ball", black round, to the plain white with black window outlines? It is my impression that the changes came once Wayne Pump Co. took over in the early 50's? Paul www.severngaspumps.com
