Verney-Carron has been there in Saint Etienne for some time. They were purported to be masters in pattern welded tubes and are noted to have adopted/advanced the "American invention choke", which was "perfected in England". Claude Verney-Carron was born in Dec. 1800 & expired in 1870 and I wonder what his quality control stamp might have been(Crown over CC)? I realize he name was Claude Verney but when he married Antoinette Carron in 1830 he hyphenated his last name.

Kind Regards,
