This has been taken apart and degunked, then put in the shed while other pressing matters were attended to. Looks like it needs de gunking again. I want to get it useable but I seem to be missing a few bits and a bit of terminology. Main thing I'm missing is whatever goes between the tool and the slide.. I have on in the pic, but its off a ML3 and doesnt fit. I have most of an ML3 if it comes to that, but that also needs work. So, whats the proper name for the wossname, and how do I identify the right one for this?
