It look like the Caunier catalog from Bordeaux. Probably Caunier was a gundealer or a store selling at least guns.
On the left page there is two grades of the Regina. Not a Darne production. I do not know the Regina. It look like to be a nice copy of the first R.
Bottom of the left page an invitation to go next page to see the famous Charlin.
I guess it is not a catalog with only Charlin product. ? question.
On the right page they speak of "the Charlin " as if the catalog is not presenting exclusivly Charlin product.
It is hard to imagine Charlin doing a copy of the R . And not to be able to make a visible improvement 30 years later.
Sorry to believe what I see.
Ready to see more.
