Pinarello Cyclocross Bike: Late 1990's? Event tubing

[Rayne_in_Spokes]

I just acquired this late 90's to early 2000's Pinarello cyclocross race bike! It is STIFF (well compared to the ultralight tubing i typically ride), quick as a fox. It has Pinarello Event tubing which seems to be one of their high level house tubesets, perhaps made by Dedaccia. Does anyone have info on this particular bike or Pinarello Event tubing?

A strange feature, it has a left downtube shifter braze on but not a right. No signs its been removed, and pics of this same model online show the same left only. Why could this be?

Frame number is L7702, and "8" all on its own
