We've had our umbrella for at least 10 years. We need a replacement canopy and are not sure if they are even still available for our model. Our base is screwed into the concrete and has 5 ribs. The sixth rib is part of the bar that rides up the main pole on the "offset" umbrella. The original canopy was green however, I would prefer terra cotta. Can you help me?

Without any brand name, probably not.
