Why are you so defensive, is there something only a few are allowed to see, are we not allowed to share data and let the assumptions fall where they may. That is why I ask for more than the serial number and the ship date. Is there a problem with knowing finish, barrel length, grip style, where shipped to and caliber? Is there something to hide? From such disassociated data many discoviries have been made or at least data is gathered as a basis for further research to be developed
