I've noticed over the years that there is some slight flaking away of the finish of the reflector of my SF turbohead (M6 Guardian) inside the shaft where the lamp assembly slides in/out. So far it's only inside that cylindrical shaft area and hasn't seemed to migrate to the orange peel area, but it almost looks like shoving in a lamp too fast would cause some of this chipped debris/finish to end up inside the business end of the reflector. I'm not going to touch this or mess with it for now because I don't think its causing a problem, but have others noticed this characteristic and is there any reason to OR good way to remedy it?
Also, how many orings is the M-6 supposed to have at the front end? Seems to be slots for 2 but I only have one.
