Hi fellas. I'm new to this site. I have a 1930 Chrysler and am planning on doing my shop up in some automotive memorabilia. My first purchase was a Bowser gas pump. I was wondering if anyone had any idea of what model and year my Bowser pump is. I was looking at a very worn plate on the side of it. It says 595 at the top left of the plate and 1 58 at the right with some serial numbers at the bottom. I thought it was probably a model 595 made from 1948-1951 but a friend of mine says it was made in 1958? Here are some photos.
