Altec Early Drivers & Horns Model..? Circa...?

Just trying to find out some info and validation on some Early Altec Drivers And Horns.<br>I believe the Drivers Are 730a’s based on some pic and general appearance but not sure. The drivers also had peerless 15100 transformers mounted on the back which I removed. They only have a small sticker on each with #20830. The Horns we’re painted  couple times covering the badges but I can make out the date made 11/11/1958. The throats and the metal end caps covering the drivers also had the small stickers on each #501598 and #20845 respectively. Any insight on this would be greatly appreciated.<br>thanks <br><br>
