Maker: Wality, but also in the case of the one I’ve got, Schrieber.
This pen, like the Wality 69, is a great big object and in an unamended form is only different from the 69 in the exact shape of its exterior; this one is more of a generically-rounded post-modern cylinder, as opposed to the slightly more traditional shape of its sibling. My example has been through a post-manufacturing refining courtesy of a company called Schrieber; for a review of an unamended version, just have a look at the page for the 69.
The refinements lie in two areas of complaint which I refer to in my look at that other pen. The piston seal is replaced with a twinned set of o-rings, mounted on a replacement shaft. The feed is also replaced with something rather more able to handle sudden escape attempts mounted by the ink.
Like the 69, this is not a great pen, but it’s a very good pen at that price.
Production Run: The unamended Wality is in current production. I hope Schrieber is still doing it’s thing.
Cost When New: The one place I could find selling the refitted pens offers them for $15.00.
