RAM stage cabs origins

Hey everyone. I was given a pair of RAM stage cabs. They were retrofitted with a 15" bass driver by PAS and the original Emilar horns had Altec compression drivers mounted on them with an Altec 2 way crossover mounted on the back. My question is this: Doe's anyone have any information at all on these cabs? They're solid, have a lot of miles on them and many more to go. It looks as though originally they might have had a small bullet tweeter right under the mid/tweeter horn. Any help at all would be greatly appreciated.
