What I see in the video about the bass:
- it's a Sabre
- the neck was defretted
- the bridge is probably a old style Sabre bridge (horseshoe)
- the string tree is at the newer EB position bewteen the A and D strings
- the pole pieces of the pickups cannot be seen
Hard to say. Could be an early EB, or a Sabre made from parts of different periods.
Others with more knowledge may be able to add more insight.
