The combination of arsenopyrite after pyrrhotite is definitely not one of the more common examples of pseudomorphism. In this specimen, the crystallographic outline of pyrrhotite is clearly visible as well as its luster. However, the mineral has changed from one to the other. This is a classic but very rare pseudo, and this particular piece is exquisitely formed and about as aesthetic as you can ask for!
