I just purchased a French SXS flint fowler with "TORDU" stamped on the rib between the barrels. The bottom of each barrel is also stamped "TORDU" and on one barrel is "A C M" and "3". Here is the translation for "TORDU"

Mr Prodi, had with Mr Poettering from the Group of the European People's Party and, after you had twisted the arms of Parliament's largest group, Mr Poettering obviously did not think he had any choice.
As you can see one of the meanings is "TWISTED". Was this the equivalent of saying "damascus"? I tested the barrels with ferric chloride but could not get a pattern...Ed
