Looking VERY Nice! Better than some of the "New" bikes I have seen in the LBS. Can't believe the number of little scratches and dings on BRAND NEW bikes that they want a LOT of money for!
Those classy old derailers can usually handle quite a range, the 79 Shimano 400FF on my LeTour handled an 8 speed I stuffed in there, but was just getting too far off-line to work right in top gear, so I went back to a 7. New tricks for old dogs.
