      Well, it's a lever filler; not a button filler. The threads at the back have been suggested to be a leftover from a previous incarnation as a button filler; that would jive with your theory. However; threads on these pens are not cast, they are machined on after the body has been machined on a lathe. The name "Eradicator" brings to mind the chemical neutralizers used to erase ink. I thought it may be a two part pen that included a separate system to deliver an ink eradicator. The presence of a "warranted" nib may be a bit of a red herring as those nibs were common replacements on all pens when the original was damaged or the owner sought a different writing quality.
      I expect the script used in the logo to be an indication of a 1920's pen, as is the material which was common well into the '30s. But the clip and lever are both generic, without any logo... it's quite a puzzle yes?

      Hmmmm.... good point about the wardens. But the clip is brass w/ a good look of rolled gold, though not marked., as is the lever. The lever hinge is similar to a Mabie Todd in that it uses an internal c-clip as opposed to the Sheaffer pin hinge. Another interesting point is that there is no country of origin on it. I believe it was made law in the early 1900's and all pens I have from the teen's on up (until recently) have country of origin. This is a real puzzle and the folks at FPN haven't enlightened me at all.
