serial number not found

Hey there, I've come across an Infinity SN fretless for what seems like a good price, but I can't find a serial number. The tuners have made in Germany marked on them, but that's it. It has a glossy finish, plays, and sounds like a Warwick, but the lack of serial has me spooked. I've looked...

hello, I bought a used bass, if I try to enter the serial number into the tool I get a pop-up not found. The bass is a corvette std with serial D 105611-04 How is it that the serial is not found? It might be a fake? Thanks
