Trying to collect rare tanks

I’ve been playing WoT console edition around 2015/2016 ish time frame. It’s like a love/hate relationship with the game. Recently I’ve gotten into trying to collect as many rare tanks as possible.

I know some tanks are impossible to collect nowadays either it was a one time event (or the developers never did it again), or the licensing expired for said tanks.

But I wanna know what type of rare tanks people in this community has and just chat about that type of thing. So far the only tank that I DO know that is rare is the American AE Phase 1 tank. I probably have more but I don’t know if they truly are rare tanks though. It seems like the developers are bringing back the rare tanks again within the shop/events.
