I think Holophane still makes them, they use the same refractors as the R47 and R7, when the utility company here takes down a cobra they keep the refractors so they can be reused so this will likely either be replaced or get a new refractor.
Edit/Update: This was replaced with a 115
I saw another 115 that replaced a R47 with an underground wiring fault along with two other lights Its really starting to get me angry, I mean its about $300 of tax dollars thrown away each time they do that I'm going to complain to the city about it
I just don't like it when they use small fixtures for 200W+ HPS, replace a fixture when it still worked, do silly stuff like put up streetlights next to each other, use wrong wattages... etc.
