Is the diary lost?

[Lu]

A man, in 2015 or thereabouts, is talking about an invention he was cooking up as a boy in 1993.

就算那个记录着灵魂对讲机进程的日记本丢失，我也能清楚地记得他开始的时候。一九九三年十一月。

 

My question: has the diary been lost, or is he talking about if the diary would be lost at some future point? I feel like if the diary is already lost, there should be a 了 somewhere in there, and the missing 了 means that he still has the diary (or at least thinks it's sitting in a drawer somewhere) and it's not yet lost. But it reads a bit weird when I translate it like that, so now I'm unsure.

 

Help is much appreciated!

No, it's even if it were to be lost. You can find examples of similar constructions using  就算on Juuku http://www.jukuu.com/search.php?q=就算 (and examples of it meaning other things as a different part of speech)

I think 我也能 only works here if he's speaking hypothetically.

Thanks both! I can safely stick with my originel interpretation then.
