I have a set of ratcheting crimpers for some very small connectors that I used in RC modeling and if I could source the anvils it would save me buying the entire crimper tool for both uses. Then I could just change out the crimper anvils and have less to pack/store. But, I have not been able to find them. It is readily apparent that they are replaceable, as you can see in one of the photos they are held in place by a philips screw on each side.
