I can't entirely make out what's stamped on the nervex BB shell, but typically that's NOT a serial number, but rather the Nervex part number and all those numbers describe the angles of the 4 sockets for tubes/stays by angles and minutes, maybe even seconds. There could still be an additional serial number stamped on the bike somewhere, maybe elsewhere on the BB shell.
BTW, a frame that uses a nervex BB shell generally means the builder lavished a little more cost into the product since those shells added more cost to the Nervex Pro package. Most builders just bought the Nervex lugset without shell and used a cheaper BB shell, maybe a cheaper forkcrown, too.
