Unfortunately, those numbers stamped on the dropout are meaningless, or at least have no meaning that anyone I know has been able to determine.
If the decals match the ones on eBay, other things to look for to identify an early Mexico are a club-only on the fork crown (later ones also have "Colnago" stamped there), long Campagnolo dropouts vs. the shorter ones, absence of top tube braze-on cable guides (the green one on eBay appears to have these, so is either a repaint or later than the seller thinks). If it doesn't have these features, it could still be 70's era, but wouldn't necessarily be as collectable as the gold one that went for $1100.
