Recent research in Japan indicates that both summer and autumn damask roses originated with (R. moschata X R. gallica) X R. fedtschenkoana. Gene, Vol. 259, Issues 1-2, 23 December 2000, Pages 53-59.
Dickerson says it's probably extinct. In 1959 Rowley reported that Graham S. Thomas reintroduced the Autumn Damask into cultivation. He had found it as a sport of Perpetual White Moss.
The Audibert catalogue differentiates between 'Tous les mois' and 'Quatre Saisons'
According to Thory 'Damascena perpetua' = 'Quatre Saisons continue' is a single form with 8-10 petals. See references (1817).
