Appearance and Finish

The pen borrows its looks from the vintage 58 and if you put the two side by side then their overall size is identical, the difference comes when you uncap the pens. The vintage pen having a much shorter section.

The modern 58 is in the meteor colour. When I'd looked at various images of the pens online this wasn't one of the colours that had captured my interest. It's certainly a very striking and vibrant colour. The modern Conway Stewarts really are beautiful to look at and you see different nuances to the colour when you move the pen in the light.
The pen has a very clear barrel engraving.

Weighs in at 15g inked.
Nib
The nib is gold with the CS diamond logo in the middle, quite plain styling in comparison to some modern nibs. The nib on this pen is a medium, not a nib size I usually choose to write with. This nib has been quite a surprise because it's not quite as wet writing as my other Conway Stewarts and it actually produces a finer line than my fine CS nibs. It's wonderfully smooth and is a pleasure to write with.

Filling system
Cartridge / converter, not really a lot to say about it. With Conway Stewarts I would always opt for a CC or lever fill.
Overall Opinion and Value for Money
This pen very quickly became a favourite. From my point of view it's a perfect size and weight and the nib is so wonderfully smooth. As stated, I didn't buy this pen new but even when the model was produced I would not have liked to pay full price for it. In my opinion, these pens are nice, but not nice enough to pay the full retail price.
