I know that the specs of an old style M600 (whilst it is similar size with M400) consist of the double trim at the capband as well as a single trim at the turning knob. What makes me curious is that certain M600 model (that I saw in ebay) do have another trim near the feed section whilst the other doesnt have.
So, does a correct M600 old style actually includes the single trim near the nib section or not? I do not think there was a replacement of the turning knob as the pen looks genuine with its single trim. (Cant find the photos which I saw last time but will search for one.)
Appreciate if anyone can help. Thanks.
