Finish strip along wall (where built-in was) without redoing the whole floor?

Q: We have a 1950’s home with original hardwood flooring. I’m pretty sure that the floors (maple?) have been refinished at least once. The previous owner had the built-in shelving/electrical fireplace removed, along the length of the living room wall, and now we see the difference in the finished floor.

Is there a way to finish the strip (14″ wide) along the wall, that seems to be unfinished and lighter in colour, without doing the whole floor? (Since this would require the whole main floor to be refinished!)

Thank you in advance for any suggestions.

A: It’s possible to get a somewhat close match if you are stopping along a board edge. However if you are doing a section across all the boards in the room you will definitely see a line.
