I got this from someone on Nextdoor in early March, but decided not to use it after all and am passing it on. Here is the original description:
"This solid oak railing was meticulously dismantled during our remodel. It was installed between floors in our split level home. Dimensions(measured outside the newels): short side - 47.25", long side - 80.5", top of the rail is at 42". Top of the newel post is 47.25". I am sure the railing could be cut shorter if needed. In addition to the newels and hand rails it comes with all the balusters, the floor strip and small filler pieces between balusters, as well as the decorative hardware covers for the feet of the newels. The newel on the end is cut in half to mount flush against a wall."
The original post is still up at the moment and has better photos than mine:
