This link says some (earlier??) Alcan powders were made in Italy by
Baschieri & Pellagri with the names of Nike & Super M Balistite

The 'AL' powders were made by Bofors in Sweden if I read the info right.

I see that the AL-6 powder can says 'Made in Italy'
Maybe a contract was started with the Italian company then cancelled,,,never marketed in the US,,,an experimental lot for lab testing??
