It's a Wayne 577-R, shown on page 329 of my Gas Pump Identification book. It was made from 1941-1949. Originally it was a non-computing pump. Someone probably put a regular computer in it because they couldn't find any good faces to put on it.
According to the picture the visi is the correct one.
One more thing, the years 1941-1949 is probably because they put these together using parts they already had, because most of their production was war material.
