I think the oldest speakers in my collection would be a pair of these (internet pic) from circa 1971, my father's Empire Royal Grenadier 9000m mk2s. They are the second edition, with a big 15" AlNiCo bass driver and a Philips dome tweeter- different to the mk1s, which used a 15lb ceramic magnet and a different tweeter. They are awaiting a rebuild in their boxes in storage. Tops are Portuguese marble.
