Identification and Value of Vintage Altec Lansing Horn Drivers with Horns

Hello,

I'm trying to identify and determine a ballpark value of this pair of drivers and 10-cell horns that my dad has had longer than I've been alive :eek:. The drivers are "Altec Lansing Corporation Hollywood 290-8" with a nominal impedance of 8 Ohms. I haven't seen literature for this specific model, although I've seen similar designs online, such as the 288. I don't see a label on the horns. We haven't turned them on for a number of years, but they've been kept indoors in dry climate. I would very much appreciate your expertise identifying these.

Thanks!

PS - If there is interest to purchase these, I will make a post in marketplace.
