The bottom of the oiler slot looks as if it has been enlarged by 3 rough cuts with a 1/4" chisel.

Why?

Not sure just got into collecting carbines have two, QHM and this Underwood still learning a lot. Not sure about the oiler slit I just figured someone did not know how to remove it and was trying to pry it out from the wrong side. Trying to figure out if it's a put together or the real thing. Just took the trigger housing apart and it looks like it has the correct parts for a underwood. But that's why I am hear trying to learn from those whose know,I could be completely wrong about what I see.
