Sorry to disagree, but I think it is wall art. I think it says 9'2 inches. Anything over 7 1/2 or 8' is a beast unless you like fishing with a beast.
On the other hand, you need a stout rod like that to pull big bass out of weeds.
Before you take sandpaper to it, check out Classic Flyrod Forum. It is exclusively bamboo rods with a repair and appraisal forum. I would suggest some type of rubbing compound that you can control. Check out an auto store for polishing compounds.
Realistically, before someone gives something away, they check it out to see what it is worth.
You can also go on e-bay and enter 9' bamboo fly rods and get an idea of the value.
