Montblanc fountain pen in blue velvet pouch

I lost my Montblanc fountain pen yesterday around 3pm. It's black resin, about 5.5 inches long, with a gold nib, and the cap bears the signature Montblanc white star; there's also a tiny star engraving on the clip. It lives in a blue velvet pouch inside a small brown leather display case; the case's lid has a dent and the zipper pull is frayed. I left it while wandering stalls along Tinker Street in Woodstock, near the antique shop, after browsing some vintage coins. It’s sentimental—gift from my grandmother—and I’d really appreciate getting it back.
