ID on 1960s Gibson 2x10 speakers?

[GarbageMan]

Guy selling these on market place says the cabinet is 1960s and that he believes the speakers to be original CTS Alcino 10s.

Can anyone confirm or deny that by looking at these pics?

Yes, alnico.

By looking into my crystal ball I have found examples of this cab with those speakers as early as 1966, but I would guess that outside of some sort of speaker warranty replacement that the speakers and cab are original to each other. So, probably 70 or 71 for the cab.
