For one.....the bolts on the top for slipfitter...mines completely different....no bolts or nuts on the top at all.....also because mine is older, the photocell bump is located different place, but I did also acquire one that didn't have a PC bump at all, but flat smooth service but that went to another member......and it looks like yours has original refractor..what bramd is the refractor? Look at the rim....one side probably either says Line Materials or McGraw Edison...the other end of the rim will have the glass manufacturer on it. Check this one, you'll notice no PC bump or the bolts/nuts on top either
Mine looks just like this and it had a LM logo in it. This looks like the Holophane lens which mine has a Pyrex lens. The only thing I want to say is the PC receptacle on mine looks a bit further back.
Nevermind, I just looked at mine and the PC is in the same spot.
Mine didn't have original glass.....also here's mine!
