i Think This one Could be a McGraw Edison....not sure.

Yes...most likely.....unless it's from 1966....because McGraw Edison took over on 1966 so I call those McGraw Edison anyway in this design

What Differs in the Design Beside the Location of the PC?
GullWhiz   [Jul 04, 2010 at 12:09 PM]
the internals......me and Don had compared our Unistyle 175s and saw our insides were kinda different....

But again....same goes for many streetlights, inside designs do change....the late 60s silverliner has some differences on the door design and the insides from the early 70s ones

im Curious...did they Ever make High Pressure Sodium Unistyle's?

Not that I know of.....the earliest cobraheads that I know that was HPS was the GE M-400A1s from 1966...
