What is the pipe made of? I see one of copper, but is the large one plastic? It looks like grey plastic pipe.
The numbers embedded, what are they made of...looks like plastic, but hard to tell.
Where does the large one go, and where does the copper on go? If the copper is the feed, it would be to a pump, so appears more modern, as does the press fit/soldiered connection.
If the large one is plastic, you are looking at modern.
