The demise of tin-lined heavy copper cookware is as overblown as the demise of sailing, riding horses, film cameras, beeswax candles, and wearing stockings with garters.
E.Dehillerin sells a large array of tin lined copper cookware - all new current production pieces by Mauviel that are constantly being replenished:

If you go to Mauviel's French language site, you will see the tin-lined M'tradition line of heavy tin-lined cookware - just click 'Francais' and then 'les collections':
If you click the English language option you are redirected to the American distributor's site, and alas no tin-lined copper.
I ordered a new current-production 11" heavy copper tin-lined Mauviel rondeau from France in November 2015. It is 3.3-3.5mm thick, and marvellous for browning and then braising meat. The tin is quite non-stick, the pan suffers no hot-spots, and the thick copper conducts heat such that the contents are enveloped with heat, permitting wonderful stove-top braises. It of course also performs very well in the oven, but so do vessels that would not be suitable for stove-top braising.
Cooks far more experienced than me have touted the advantages of heavy tin-lined copper cookware (see boilsover above, and the many photographic examples he provided of copper pots being very much in evidence in professional kitchens). As mentioned above, Julia Child was a big fan of tin-lined heavy copper cookware (just don't follow her cleaning instructions). When she was developing and testing the recipes in her 1961 classic Mastering the Art of French Cooking, she did most of that using tin-lined heavy copper cookware she had bought from E.Dehillerin. If tin-lined heavy copper cookware was good enough for developing one of the greatest and most enduring cookbooks of all time, then that's good enough for us mere mortals.
Julia Child would have been excited to see the quality of cookware now being made in the USA by companies such as Brooklyn Copper Cookware. I just wanted to bring attention to this old-world artisanal approach to making copper cookware for those who value slowing down to make good food, drink good wine, and enjoy good company while respecting tradition and indulging in the finer things in life.
