Another "close but no cigar" would be a 1984 Centurion Pro Tour. Same frame material and even paint color. Same odd combination of two downtube bottle cage bosses. but none on the seat tube. But different seat cluster and definitely different fork. Odd that this fork would not have mid-mount low-rider mounts. Replacement fork?

Still, it's in that "league", meaning a fine grand-ish tourer.
