I had the opportunity to inspect and play this bass in 2012 when it was first being offered by 30th Street Guitars. For some reason, the last digit of the serial number is very difficult to make out and you would probably need to take off the neck to make a final determination. But I don't think it's been deliberately altered either, just a tougher one to read through the Lucite. Currently for sale at $1,850 or best offer.
