Are you trying to say Rich Law has now been fooled and used faked sniper in his published documentation? Richard Law seems to be well respected author with number of books written on the K98k.
People been telling me how bolt handle relief cut can only be on cigarette rifles, that "it wasn't use on military snipers". Well that doesn't appear to be the case anymore based on what I found in published books on the subject. So with this regard specifically to the bolt, yes it is evidence/provenance.
Ahahahahahahahahahahahahahahahahha
There are several documented and proven fakes in his books......
One of the reasons his books are so outdated, and should not be relied on for anything but very basic reference.
