New Super Dearman antique tenor saxophone - testing

I bought this beauty on my holiday in St. Ives, Cornwall. I think it is at least 55 years old and it plays!

It came with it's original box with a label saying John E. Dallas and sons ltd, Ridgmount St, London, WC1. Serial number 10975.

I would love to know more about this saxophone
