I wish I knew where to begin with this one. Kralik or similar? Signed in excruciatingly small letters.

Any help on this lovely unusual aurene piece would be most appreciated. I purchased it quite some time back at an estate quite some time ago because I just really liked it for some reason. I went to clean it recently and noticed a signature. I'll probably have to wait to get a new scope to ever figure out what it says. I thought maybe someone could give ma a place to start.
