Recently, I got another piston filler from ebay that is probably rarely seen outside of Germany. The Senator “Windsor”. Judging the quality, I would rate it clearly below the “Regent”. It is a very smooth writer, puts down a finer line than a medium Pelikan M200 and is about the size of the Pilot 78G. Mine came unused with packaging and manual and so far, I dipped it only in ink to check the general writing characteristics.
