Mauser's Rear Frame "Bump"...?

[BILL]

It is interesting that people are not more forthcoming in 'revealing' the full serial number. I know it has been discussed and explained that 'exposing' the full serial might lead to legal problems down the line (i.e. a stolen pistol or a spurious claim by a con-artist that said pistol belongs to him). Actually, I don't see that happening often and if it were common would Ralph Shattuck or Jan Still or anyone, for that matter, advertise or allow photographs that list the serial number? How can someone expect to find out more about their pistol if they can only tell you it is serial# 396xx? Does that mean it might be 3969a? or 3961x? hard to figure. Maybe someone needs to tell me again why it is so reckless to divulge ones serial number.
