Hello Vic
Please don't take this the wrong way , but ...
If the cardboard box looks too good then its a reproduction in my opinion.
As an example - a few years back I bought a boxed Webley Target.
Fantastic condition pistol with a really near mint box.
It was expensive.
But there is no way the box could have been passed off as a mint box.
You just know.
No insult or disrespect intended
