First let me say thanks to all who helped with the glass cleaning ideas, the Barkeeps with the 0000 steel wool did the trick. My pump's Name Plate Tag was missing when I bought my pump. I purchased a reproduction however all the information is blank, as you would expect. Other than the Model number, I have no idea what would have been the Type,the Serial number series or the Underwriters number. Would some one who has a 300, with a tag give me some ideas. Thanks again.
