As you all saw, I edited my chrome-plating translation, originally chromed barrels into "chromed bores" for more precision. Here's a photo of the St. Etienne proof mark which looks like the diamond has ISR in it, correcting my earlier note.

Gun is a 16 gauge F. Darne fils aine recently rebarreled but with ordinary proof and no chrome plating.

Regards, Tim
