That L & N hand stamp looks like it could be L & N Railroad.
I live in Louisville and have sold lots of L & N Railroad tools, they are always marked the same way either L & N or L & N RR in the same type of block letters.
Most all tools were made in the L & N shop and stamped just like that.
Once I found a super heavy duty spatula cooking utensil , and it was marked L & N RR I asked an old man that used to work at the L & N repair shop in Louisville and he said, .... yea we made everything.
I don't know what the E S mark might be.
May not be L & N RR but looks like it could be.
