Thanks for those pictures, interestingly although they are similar there are some differences - mine has spring loaded plungers that push the wedges forward when the pressure is released. I agree that it needs to be taken apart, cleaned and lubed and that may be all it needs. When I get time to do that I will post in the shrinker stretcher section. And yes it is very heavy duty, my back can attest to that!
