Yes, the visors are mounted for a vertical orientation, and you could easily change that to horizontal if desired.

Up to you. I like green as you have there, as that was very common where I grew up in NJ a few decades back. Looks like that signal could clean up nicely without repainting.

Again, up to you. That signal is designed to be mounted either way.

Kinds looks like an LFE from the 70s or 80s, or a MARK IV from the 80s. It could have come from almost anywhere, but I wouldn't be surprised if that was from NY or CT, given the kind of visors and paint.

See Jerry's comment, seriously. If I saw it for sale, I would pay maybe $20 because I don't really need it (despite it's being cool). Someone else may pay many times that amount...how high...I dunno.
