thank you Fernando !!
I looked about the lot stamps you told me and found a site about these lots
if it's like that, it will be an old austrian model of hunting dagger
( silver 812 as you told me ) Pretty cool if it's like that !!

( the T in the O on the blade of the small knife looks too like the old stamp )
Perhaps do you know how we can test silver authenticity ?
Kind regards
