Questions for a new Luger owner

[Mauser720]

Phil -

This is not a particularly good photograph of a so-called "double date" Luger; however, it does show the "1920" property mark on a 1916 LP-08. I think you can see that no attempt was made to remove the original date of manufacture (1916), and you can also see that the "1920" is more crudely stuck too, which is typical.

This photographs appears elsewhere on this Forum.

You have an interesting 1921 example. Someone who knew what they were doing certainly made a unique take down lever.

Hopefully this contributes to some understanding of the frequently misunderstood "double date" issue.
