I will have to wait until I get the frameset back in a few months. The last time I painted it myself the paint on the BB was rather thick and I had a hard time reading the numbers, so the recent 5's on the fork could have looked like 6's on the BB. I'm fairly certain the numbers are oriented the other way, number tops towards the head tube. When I recently dismantled the bike the numbers on the fork were plain as day and I made a point of writing them down on a piece of paper. Perhaps my bike was simply accounted for internally as a Chrono, but I ordered using the 72 catalog in which the Chrono doesn't appear.
