Agreed -- Just looking for individual spikes in the harmonic spectrum is naive. However, I think even if you have a good idea of which instrument it is there are other factors involved which could make matching a generic instrument model more difficult (e.g. the player, the playing space, instrument variations, etc.). For instance with the french horn (it's what I know) there are sometimes drastic differences between players and instruments -- the most stark being possibly the vienna horn vs. the usual double horn.
