I’ve got a Senator shorthand pen waiting to go into the Museum at some point, so it’s quite handy to have a bit of history on them. The one I have still works ok. The piston filler is a bit stiff, and the nib is a little disappointing. I thought a shorthand pen would have a nice flexi nib, but it’s actually only slightly flexible. Still, not a bad pen, and writes ok, if a little scratchy.
