This is a Wayne 500 that I did for the Carnegie Museum of Art in Pittsburg, PA a year or so ago. They wanted it exactly to spec as to what it would've looked like from the factory. I was able to get a complete set of nos literature from Jack to go with the pump and they wanted the ad glass to match the pump in the sales brochure instead of branding it. The OPW 811 is the correct nozzle for these pumps in the era they were manufactured but due to the useful life of a pump, many others were used over the years. Your 505 is looking good, be sure to post the finished product. .....GB
