Aerographic/aerial films in 8cm width ?

[removedacct2]

I have bought 2 rolls of aerographic Tasma from the 90's. It's perforated, not 70mm but 8cm width by 1900cm length. Will cut to 120 rolls.
Was thinking I could find some old roll of Agfa in same size, so to compare, and it will arrive before so i could start playing making a cutter.
But if there are older brochures for Aviphot mentioning all kind of sizes, also 8cm, I can't find actuel rolls at the usual online second hand places....
