Kensal, I probably used the wrong terminology to describe the lower projection from the joint roll that's set into the frame, but there is a knob there on ejector models that will prevent an extractor forend from fitting onto the ejector gun's frame. I only suspect this because I have an ejector Parker that suffered the loss of the original forend, which was previously replaced with an extractor forend. That knob had been ground completely off, and it functioned as an extractor, but when my gunsmith fitted an ejector forend to the frame, the ejectors didn't work due to the absence of the knob. He welded a replacement knob onto the joint roll, and the ejectors work fine now. At least, that was my deduction. Perhaps there was some other reason why that knob had to be filed off when the replacement extractor forend was fitted to the ejector frame. I don't know. Presumably, the ejector control rods attached to the hammers which protrude through the front of the frame would also need to be removed during the conversion, as they were in my gun.
