Jakub, I think Charlotte knows what the tea is... she's just asking our opinions from the pictures.
If it is a shou, then it's possible it wasn't fully fermented, which is why the leaves still have a decent amount of integrity to them. Highly fermented shou tends to be much more scraggly than that, and you almost certainly wouldn't be able to open out a leaf like that extra picture you have without it breaking apart into bits.
If it is a sheng, then it is very old... I would guess earlier than 1980.
So that's my guess -- either younger not-fully-fermented shou, or an old sheng. That's as far as I can get from the pictures alone.
im a complete amateur, so for me just by looking at the colour of the soup you see in the upper right corner it is sheng..... also the leaves look more intact than usual shou.. but you can never tell, i thikn it could be both... well i mean thats what im guessing im a complete amateur.... for me it could also be aged rock tea, or any tea.....
It was given to me as a sample and listed as a 1980's raw tea, stored in Hong Kong. I am not sure if that is actually what it is or not, but it tasted like wet storage for sure!! I also thought the first picture of the leaf was pretty important, as I never see shu with full leaves like that, and there were many.
