I have a Dickson quick change tool post. I just found one on ebay that is how I determined it was a Dickson. Up until now I didn't know what it was. There is not a single mark of any kind on it. Does anybody know how you determine what the size is? Between the "V" it measures about 80mm and height is about 95mm. I am trying to find tool holders for this unit. There is one on Ebay also in GB but I'm not sure if is the right one. Any help?????
