that's an oil cup, not a Zerk (grease) fitting on the BB.
Those transfers (decals) look like something used on china tea cups, I have a strong suspicion that they, and the head tube decal, were added after the crude re-paint, and these offer no clue to the real ID of this frame.
The lugs and forkcrown are probably the only way to ID this, and I don't recognize them...yet.
