I've noticed on one of my student oboes (Buffet 4121) that the F resonance key is open when the instrument is at rest. normally this key should be closed in rest position. However the instrument seems to blow OK.
Any ideas about this-does this vary from instrument to instrument?
Thanks,
Simon

Depending on the mechanism - on most conservatoire systems the F vent is arranged so it's fully closed and only opens when RH3 is held down and RH2 is left open (and closes when you close RH2) and on most thumbplate systems closes and opens along with RH2.
If it's a basic thumbplate model Buffet with simple 8ve keys, then it'll remain open until you close RH2 which is how pure thumbplate system oboes have their forked F vent set up. Howarth S10 and S20 oboes have the same arrangement as do Ward & Winterbourn, B&H Regent, UK spec Bundy/B&H "78" and the Italian import thumbplate systems that have the forked F vent fitted (Howarth B, Selmer Sterling/Console/Gold Seal, Rudall Carte LM5, etc.). B&H Imperials have the open standing F vent, even on conservatoire systems and this can play havoc with the conservatoire system Bb fingering (xxo|xoo) which is why con system instruments have the closed F vent arrangement.

Thanks -presumably this means that when thumb plate models have a closed F resonance key it means it is a dual system -have I got that right?

Dual systems being primarily conservatoire system instruments with an added thumplate will mostly have a closed forked F vent - there are some exceptions like B&H Emperors and Imperials as they're a bit backward as far as oboe evolution goes.
