Gibson later went to a 3-point bridge, which doesn't tilt. Unfortunately, the big holes bored in the body for the improved bridge are in a different place, so if you want to switch bridges, you have to figure out how to plug two holes about 1/2" in diameter that will show (I've been pondering this one for quite a while....more knobs???) The newer bridge has big hook-shaped things on the casting which grab their posts, so it's pretty easy to tell the difference.
The necks on these basses are pretty stable over the years and pretty fast. The sound was great back in the days when we all had a pair of 15" JBL D140's and plenty of power, but it was back when folks thought that bass should be more felt than heard and definition wasn't as desirable as it is today. Most recording engineers hated them because even with all the treble cranked up the sound was still pretty muddy and boomy and they couldn't do much with it (that's why there is a Precision pickup under my handrest and stereo wiring). The EB3 with the added bridge pickup was better than the EB0, but it still wasn't very crisp by today's standards, especially back when everybody used flats.
I get a big kick out of people spending $1,000-$1,500 for an old EB and treating them like they were something special. Back then, they were a decent, fairly inexpensive bass, and that's about it. Most people who bought them did so because they couldn't afford a Fender, Ric or other top of the line instrument.
