PenBBS 308 and Lorelei 019 pens disassembled

The PenBBS 308(-20SF light blue ‘Glaze’ demonstrator shown here) and Lingmo Lorelei 019 (with two of the green acrylic variants shown here) are more or less the same pen, and the parts are interchangeable. However, even though both models are fitted with nibs that are slightly upturned at the tip, they seem to write quite differently; and I like the Lorelei's nibs better for the line widths it puts down, even though the PenBBS nib itself seem to be of slightly better quality in terms of material and manufacture.
