Hey Andy. Looks genuine to me. Old bridges were different than modern ones. They also came with a single truss rod. I do find a second truss rod an important enhancement over a single.
Using batteries on a series model will be costly, from what I have heard, as they use a lot of power. I only put batteries in mine for the convenience of using the tuner, or similar circumstances, without having to turn on my whole setup.
See the threads on upgrading to modern electronics, unless you live in a rural setting, to let you know that this bass could cost you $1,500+ to use hum free. Something you need to consider, if it would be used professionally.
Adjustable blank nuts are @ $35 and I am sure you can buy a new bridge, but then it takes away from it being a 'vintage' Alembic. However, I am quite curious at the price of a new bridge, so I will look for to an answer on this one. Note, to have Alembic do the nut, it will probably cost @ $250+ for the nut, shipping, and labor.
You can look up threads for making your own five-pin cable, and if you are moderately proficient in building electronics, you can build your own power supply. Members and staff have supplied 'blue prints' for these. Otherwise, cords are $195 and power supplies (Rackmountable) are over $400 now ($425, I think). Other expenses you need to consider in the purchase of this bass.
I am not trying to talk you out of the bass, just trying to give you an idea of the final price you may be looking at, depending on how the bass is used. Bottom line - Something is only worth what someone is willing to pay for it. I hope this helped a bit, and others can give you more definitive answers, I am sure.
