    Default Pelikan Souveran Inner Barrel Sleeve?

    I've read a comment somewhere that claimed that Pelikan Souveran series pens have barrels made of cellulose acetate with a nonreactive inner sleeve to protect the barrel from the harshness of inks.

    Can anyone confirm if they have a non-reactive inner sleeve?

    Thank you!

    The Pelikan's Perch quotes 2019 Pelikan company M800 literature that, "The barrel with brown and black stripes is crafted out of is crafted out of high grade cellulose acetate which is then turned into a sleeve."

    This is a Pelikan 800 barrel minus the striped binde, a full exploded view below that. All of the Sovereign pens are made with the same basic pattern, i.e inner barrel of a transparent material, with a nose piece that the section is glued onto. Only the 800 and 1000 pens have the brass thread bushing. The lower pens have plastic threaded, or snap fit bushings. Rollerball pens start with the same inner barrel, section and binde. They have a cone that screws into the section, a brass sleeve in the barrel, and a different arrangement on the grip knob which eliminates the piston mechanism which is replaced with a spring loaded plug.

    I assumed that the material was acrylic because of the way it responds to the same solvents, but it could be cellulose acetate. I haven't tried using the celluloid solvents on the material so can't confirm. It is not completely immune to the effects of weird ink. Speculation on the part of Pelikan service is that some of the dye saturated inks are the reason why the plastic weakens and the nose piece snaps. I would agree that the binde is cellulose acetate. This is a relatively thin sheet fit, rolled into a tube that is then fit on the barrel and secured with an adhesive. While not common, we do see cases where the binde spilts, in extreme cases the full length of the barrel, or where it has come off of the pen.

    Thank you, Ron. This was just the confirmation I was looking for.

    Being that it may be cellulose acetate, would it be wise to stay away from alkaline inks?

    I'm quite sure the inner sleeves are--and have always been--acrylic. I believe this even goes for the 1950s models, which explains why they so rarely have the level of ambering seen with their contemporaries.

    I read somewhere years ago, when the M300 came out that the M300 had the brass part in the piston mechanism. Is that true?

    IDK if it is in the first gen M300 but it is supposed to only be in the M800 and M1000.

    I don't know that I've ever seen a brass bushing in anything below an 800, vintage or modern.
