We have been searching for old regional varieties; this was introduced by Thorburn's in 1893 in NY. Bred by Elbert Carman, who was an eminent breeder of his time.
Their description is a follows...
"The color is a pure terra-cotta—quite unlike anything ever seen in a Tomato before. The skin is lustreless and slightly downy, like that of the " Peach. ' In form it is also unique. It is rarely acutel3T or deeply lobed or seamed. The surface is slightly wavy and the undulations gradual or obscure. The flesh, too. is peculiarly arranged. Just underneath the flesh of the skin are the pulp cells in which all the seeds are imbedded. The central portion is solid flesh of a mealy, tender consistency and of a mild flavor, peculiarly agreeable to those who prefer raw Tomatoes. The vines are marvels of productiveness, beginning to hear early, and continuing to ripen fruit until frost. Per packet of 20 seeds, 25cts." - Thorburns 1893
Fast forward to 2017: These are really striking mid-sized fruit. They do have a thin skin and will start cracking in wet conditions.
