Hey there it would almost be impossible to give something a name without knowing where it came from. Like with old school strains even name like og kush. Northern lights, green crack, ect. Even if you were to have the same strain from a different source it would probably still be quite different.
That being said seeing it is an old strain I would guess it is either some kinda underground og kush that was going around wherever the seeds are from back in the day or it’s possible back then he was able to come across some white widow, or skunk, or critical something like that there old strains that ppl made in the eu back in the day. A lot of underground growers back in the day would get ahold of the eu strains and grow those or start crossing them with street weed for then they had seeds for
I would guess with the froth pattern something like skunk, critical, or white widow just with how the leaves look and the way it’s stacking like that
Maybe pray to the weed gods and they will bless you with ancient stoner knowledge
