The Lamy 27 is built exactly like the 2000. Rather, the other way around. The section screws out, and the nib/feed/collector unit can be pushed out from the nib side of things- again, just like on the 2000. I've never had a reason to remove the piston from any old Lamy or Artus pens, they all still
work like new, even after 60 years in some cases. I believe the piston is friction fit, but I'm not entirely sure.
I've never run into a 27 or 27-based pen whose section didn't unscrew fairly easily- never had to use section pliers or anything like that. I have had to do some ammonia cleaning to get the nib unit out, though.
MYU has a lot of experience with Lamy 27s as well, and a few other people. They're a really great pen to "restore," because other than nib cleaning and adjustment they usually just work.

Thank you for your help. I now have the section out of the barrel. The end of the thread part of the barrel is a bit rough is this normal?
