The mark on the handle looks like it might be "H.W.L.":

while the mark on the laffe/bowl is the "Twins" logo of J.A. Henckels of Solingen, Germany:

This particular twins logo was adopted in 1900, so the fork isn't any earlier than that, though it looks more like it's a thousand years old! Which brings up the other issue...
Can something in this terrible of a condition even be restored?
