I don't know how many miles were on it, that engine had been swapped into the car at some point. Most of the eight to ten water pumps I have removed looked as good as yours. One had some slight scrapes on the blades from bearing play, one had clumps of congealed coolant from improper coolant mix. I think they all had the original gasket, so first time changed. Call that a catastrophic failure rate of 10% if left 'till there's a sign of trouble (in my experience). All four IMS bearings I've removed (with over 100k miles on them) have looked great too.
