I put photos at the link. I’m using an iPhone, so I’m not sure they are sharp enough.

I’ve got a new (to me) Visconti Homo Sapiens with a medium 23k nib. It writes well, except that it hard starts and occasionally skips on a down stroke. There’s something about a downstroke that really befuddles this pen. I’ve tried various angles and pressures without luck.

I may well send this to a professional, but I wanted to get an idea of whether this was a repair I could even begin to undertake (I’m an utter novice).

Thanks,
Tom
