Yes, I have a much loved Sonnet. Like yours it's a black lacquer, but a later version with the wider band. I love mine and use it daily. It's well travelled too and as such has significant sentimental value. I dropped it a few years back with the cap posted. Murphy's law held true and it landed on its nib, bending it badly. I ordered and fitted a replacement and it has given me fine service again. Like my seiko timepiece with an automatic mechanical movement, it's a treasured companion that's never far from my side.
