Lovely frame! Nice tube set. Should be a lot of fun reviving that bike.

Thron is a mid-high range tube set made from Cyclex. As it was introduced in the mid-90s, I assume that lowers your frame's age slightly.

All true. The "super" on the tubing decal relates to the tubing itself and not the frame model. There are features that need to be shown in detail (bottom bracket, stay caps, etc.). "SL" was also "Cyclex" alloy, but "Thron" (introduced circa '94) was butted differently. It weighed more (per specs) than "SL" for a frame the same size which may be due to the stays; but I am unfamiliar with the Thron/Thron Super tube sets, and what their butting, fork blades/steerer, and stays, were spec'd as compared to "SL" sets. Another thing to consider is if the builder used a complete Thron Super tubeset (if indeed it was available; I would need to research it), or if those "C" model steel frames were a mix of Columbus sets, and/or Colnago proprietary pieces which was not uncommon back then, same as it is today for quality/custom frames depending on their designed use or rider demands.

The front derailleur is unknown to me. All the Campagnolo units I have seen have logo marked cages. It looks like a nice one aside from the cage damage (limit screw improperly set).

I agree on the FD not being a Campy part; but I don't know its make either.
