In regard of dots arrow 2 I think they are traces left after hard soldering repair (I have done it, too). Nothing to worry about.
The problem is soldering line (arrow 1) as if the bowl was attached to the handle at this point. Normally, spoons are not made this way, I mean soldering the bowl to the handle, they are supposed to be one solid piece. But I cannot judge every spoon, you know better if yours was meant to be made like this when compared with similar spoons of that period and country. Or the line is another repair between the bowl and the handle.
