Both those photos are actually of the EX1. Here are some photos of my C1A1 and C2A1:
I have seen a number of the NZ marked Sterlings make it onto the Cdn market, along with NZ no8 rifles and, of course, NZ marked no4s. But for some reason the NZ FNs did not make it into our market. When were they phased out of service? It may well be that they got released after the FNs became prohibited in this country.
The Canadian and the Australian FNs are very similar. There are rumours that the Canadian Arsenals Limited made some of the barrels and parts for the Australian Heavy Barrel FN, although I think I saw somewhere that this was not true. Our early C2 top covers ended up going to Australia and (with some modification) used on the Australian HB FN.
I need one of those top covers for my collection, and of course, since they were almost all exported, they are very hard to find here.
