Nope not Line Materials.....I have suspecitions Westinghouse made those arms.....we have those in PEPCO as well as the Line Materials one.....maybe Joe M. would know.....I remember he identified a Westinghouse old radial wave or a tear drop and mentioned it had a Westinghouse Arm....but it was an older style arm....but a lot of the fixtures with above arm I've seen holds silverliner or AE 13-000 but I've seen LM sometimes mix and match happens.....but normally its AE 13-000 or silverliner at the oldest
The Arm above does look similar to a Line Materials...but the mount is different...this one has a flatter right triangle mount on the sides....the LM has more wavy instead of flat and not triangle
Good pictures, they do look similar as a Line Materials...but note more triangle shape than a LM and notice the grooved triangle in the triangle itself?
