Here is a very early 979 frame looking really nice with gold tubes
I say it's early because it's got the horizontal pinch bolt for the seat post but it has external routing across the top tube for the rear brake cable and because the "Vitus 979" on the fork is a stamped in logo rather than a decal.
Unfortunately this bike sold on ebay and the seller did not include a photo showing the serial number on the bottom bracket lug.
