I have an SC 3 # 100 engraving pattern. It is deeply engraved and quite the looker. My wife has an SC 3 w/ game scene engraving w/ the dog facing the wrong way (an error) which according to Perazzi is now a one of a kind.
On the pigeon circuit , I have seen some beauties. SCO sideplates , etc.
Also some Fabbris that are out of the ordinary , incl (supposedly) the only funeral model.
