Sorry I was asleep at the wheel and didn't see the inquiry.
I got my pair 20 years ago from a welding supply store that's used for crimping welding hoses. It is a visegrip brand which I believe is still available. There are cheaper generic sets out there too. A web search will uncover lots of sources that might be easier to obtain for one's locale. Ferrules in stainless or silver cad plated brass should be easy to find through the internet or a hose supply house.
