Isn't a UN70 Dura Ace grade?
I agree with dddd is the spindle turns smoothly there is no reason to replace it.
I do not have alot of miles on my Phil BBs but they seem very nice to me. When I considered the cost of new Record BB for '99ish group compared to the fact I doubt the original had more than 5k on it I went for the Phil.
There is company on the 'bay selling some nice looking and seeming well builf BBs cammed Omni Racer, I put one of their BBs in my Batavus a few weeks ago. it seems pretty nice for the price.
