According to the owner, they seem concerned that the printing on the grip is too thin and that the internal mechanism isn’t the long version.
Personally, I’m also a little bothered by the fact that the font used for the hardness rating is on the thin side. This is because the grip has thin lettering, and it feels a bit off that the font for the hardness rating isn’t bold.
Also, based on my own speculation, it seems highly likely that the grip has been replaced.
I only have one exemplar from each of the 3 periods for the 0.3mm and (IIRC) a late period 0.5mm.
I have heard complaints about grips being switched, but I am not that familiar with the internal mechanism to be able to tell if mine have been switched.
These are just way too expensive to build up a large collection to be able to put together a timeline of the differences in all of these.
There are some collectors out there who have most of the Mechanica releases. I know at least @xiaozhenyang4444 has a lot of knowledge about this model, although I don’t know if he still possesses the entire range.
