I have a very nice old Mueller I found in a antique store.. I wish I could tell you the year it was made but no date on it... When I was restoring it I had to replace the two small nozzles because they were both odd sizes and not two and a half inches but more like two and a quarter inch 🤔 Couldn't figure out why that was but I removed those nozzles and replaced them with a standard two and a half inch size! Had a hard time finding one's that would work but I'm pretty resorsful . This hydrant only has the name of Mueller, Chatta.Tenn., and 41/4"... As I mentioned,no date...
