Interestingly, I watched as usual ebay and found this lot. Inside there is a very interesting photo.

In the Russian Museum he is not.
I wrote letters to them and called them.
They do not know where the knife.

And here is his mark!
Apparently, he is at the master Greg Wall or his friend.
Photos are fresh. The knife is clearly in the USA. It's good.

I think we should try to contact him and organize a photo session
