I'm pretty sure that these three are Gamewell Diaphones, am I right?

However I have no idea about these next ones:
This one looks similar to a Gamewell Diaphone, but there are differences.

I'm not sure if this one is the same kind as the one above or not; it looks a little different.

Finally we have this array here. These horns are all a lot shorter than the ones above. It looks like two of them are the same kind, but one is smaller. I have more pictures from different angles (unfortunately none of them turned out well for some reason...) if it's hard to tell from this one.

Any help will be appreciated.
