You all are correct. Upon closer examination of the Columbus decal (with reading glasses this time), what I initially believed to be 84 is in fact S4. Here is the entire descriptive text on the decal:
Gilco Design
Profilo S4 Costruito per Colnago
Can we estimate the date of manufacture based on the Shimano Deore XT 6-speed indexed gruppo?
