1984 Norco Avanti SL
Your Avanti SL is from September 1984. That's in the grey region where it could be 1984 or 1985 model. The SL ("Super Leggara" - they spelled it incorrectly) was quite a step up from the original Avanti of 1982. The tubeset was Ishiwata EX CrMo versus hi-tensile steel, The rims were aluminum versus steel and the front hub was spec'd with a quick release. The brakeset dropped the safety levers and was upgraded with hoods. Pedals were also upgraded to an aluminum quill style. Gearing was tighter, courtesy of a 14-26T freewheel. The frame rec'd forged dropouts, top tube cable tunnels and bottle bosses.
The standard Avanti was still in the 1985 lineup and by that time had rec'd upgrades of top tube cable tunnels and aluminum rims but the derailleurs had been downgraded to an Honor/Spirt combination.
I see you've replaced the brakes on the Avanati SL but everything else looks like it could be OEM, excepting consumables.
