I had a similar French guild sxs 16 bore for a few years. I bought it at a small gunshop in Maine for $375. It was a 68 cm barrel 65 mm chamber ic and F gun that had probably been used for grouse. The gun overall was in good condition inside and out with only some deterioration of the nickel plate on the action bar. Weighed 5 pounds 11 ounces. First thing that happen was it began doubling with B&P one ounce loads (2-1/2"). I adjusted the sear and went on for several years, using it to hunt grouse and during dog training. Then it started to fail. It developed a light primer strike on one side. I sent it to a gunsmith and he found a broken main spring/replaced. Next thing that happened was it actually fired when the action closed! Back to the gunsmith. He said the metal used for the sears was very soft and he actually welded new metal tips and reshaped the sears. Back to good operation for a year and then I sold it...I believe this gun was quite old, had a serial number 408...Possibly pre WWI.

18.3 was the exact measured size of the bore, 9” from the standing breech, as measured by the proof house. It is very useful to quickly determine if the original bore size is altered from the dimension the gun passed proof at. Do not sneer at single French proof, it is quite stout. You can use a caliper at the ends of the barrels to ballpark the choke that is left.
The older I get, the less confidence I have in measured choke, one must pattern the gun to see what one has, with the loads you are using. Off the cuff, European guns seem to pattern tighter than they are marked in my world, ammunition differences are the likely culprit.
Good luck with your new to you Gun.

Best,
Ted

interesting to note that the example on the left lacks the typical solid stop on the left indenture of the lever....that is a feature that i have come to automatically associate with the VC and it's many copies...

best regards,

Merci infinitivement fab500. -

Been out for a day.. The story of Jean-Pierre Didier is utterly interesting (And that on-line translation is better than mine I must say - though not as fun).

However, the story of Didier-Drevet as presented (In the machine translation) doesn't quite mesh with some advertisements and previous postings. I think actually fab500 is referring to the "Dating early 20th Century French Guns" line. This line dates 1889-1912 French guns based on the dates on Didier-Drevet Eureka Plume barrels. From 1889 to post June 11, 1912, Saint-Etienne guns used cm for chamber length.
https://www.doublegunshop.com/forums/ubbthreads.php?ubb=showflat&Number=484199&page=12

What we previously assumed about Didier-Drevet and its successors will be analyzed. The machine-translated post will also be re-read. There are members of the family mentioned in the post which need to be looked-at.

Previous texts show Pierre Didier-Drevet retiring in 1900 after his gold medal in Paris. His firm was then bought by his former employees Gerest-Berthon. The barrel-making part of the company, which was supposedly continued separately by a son, is new information.

(You have to be just as careful about French language "authoritative" posts as you do in English)

I bought a Gerest-Berthon 16 gauge SxS chambered for "7 cm" - with a 1906 dated Didier-Drevet barrel - which inspired that investigation.

Love this, but it should be posted as a separate line. Gene

Larry, actually VC trademarked three names for his top key:

HELICOBLOC
HELISTOP
HELICE-GRIPP

Pretty's sure VC occasionally used "Helice-Grip" as well. Could you please post again that graphic of a VC Key - I seem to have lost it.

And Lawrence, someday I'd love to come across the river to shoot with you all....not that I'd light up the chart - shooting like crapola these days - but it gets lonely shooting a SxS at Bull Run. (at least people aren't wearing masks out on the range).

Argo, I've never shot at Bull Run but last Sunday at BCC IWLA I shot a round of Chinese Trap, the guns being shot were a Woodward Single Barrel Trap Gun, A Fox Single Barrel Trap Gun, a 20 gauge California Duck Club Parker and my Ithaca NID Super 10 double. That's cooler than usual but still BCC is a great club.

Found it. VC turned the top key screw upside down...then added a lock down the barrel. He made his money on these innovations. "Helice" was never mentioned anywhere in his patents.
