There are at least 4 distinct quince varieties which include “Krymskaya” as part of their names:
Крымская Ароматная - Krymskaya Aromatnaya - Crimean Aromatic
Крымская Ранняя - Krymskaya Rannyaya - Crimean Early
Изобильная Крымская - Izobilnaya Krymskaya - Prolific Crimean
Яйцевидная Крымская - Yaicevidnaya Krymskaya - Egg-shaped Crimean
Which one of them is the one marketed as Krymskaya / Krymsk / Crimea is unknown to me.
As for Aromatnaya being the same as Krymskaya / Krymsk / Crimea. There is a distincs variety called just Aromatnaya, different than Krymskaya Aromatnaya, so who knows.
Here are the descriptions and genuine images of Krymskaya Aromatnaya and Krymskaya Rannyaya directly from their breeder:
