In my own little world, I have been and will continue to consider them T206's. Whether or not the collecting community jumps on board with the few matters little. BUT it sure is fun to study, discuss, etc.
Edited to add--
adding T213-1's to T206 doesn't add any more subjects to the T206 set unless, of course, one is considering a master set.
