Ted:

Geoffrey Gournet had (and maybe still has) a 28 gauge Darne in the white, awaiting a buyer who will decide how it's to be engraved. The asking price, the last time I saw it, was over $13,000, before engraving, which I didn't even ask about, as the gun was already well out of my league.

I do have one of the very small handful of 10 gauge Darnes. At 7 pounds, 3 ounces it's light enough to be a nice bird gun. Probably very late 19th century, although Mr. Gournet could not say for sure. 2-7/8 inch chambers. RST's shells have worked quite nicely in it. Choked 20/1000s and 35/1000s. I have far more in it than I'll ever get out of it (rarity notwithstanding - how many people are there looking for a 10 gauge Darne? My guess is none.), but I enjoy shooting it and it does get attention at the local clubs when I take it out for exercise.
