I just obtained an 11C which appears to have no serial number anywhere. Also, it differs from two other 11Cs I have in that the keyboard overlay has a matte (nonreflective) finish rather than glossy. The 11C logo on this unit has a bright silver (mirror) finish. My other 11C has a more of a matted silver 11C logo (the third one is missing the logo).
Does anyone know where I can find the serial number on this unit? It does not appear to be altered. I've inspected the area where I'd normally find the serial number carefully, but it looks clean and uniform throughout with no signs of alterations or tampering. The rest of the body appears the same (clean, uniform, no signs of tampering if serial# has been somehow erased).
This unit is very clean overall (maybe a 9.6) so it would seem it "should" be easy to find signs of tampering... but I don't see any.
Has anyone seen such an 11C (or any other Voyager series calculators with similar features)?
Thank you in advance,
Sam
