Shamelessly poached from elsewhere on the net.....
To give it its proper spec. Birmabright BB2, Produced by Birmetals
Ltd., Birmabright works, Clapgate Lane, Quinton, Birmingham. Now
defunct . This material could have also been called Hiduminium 22 ,
Alcan GB M57S , BA 21, Alcoa 510 , AWCO 21 . These being the same
thing, but produced by other companies of that era. But we only know it
as Birmabright, because thats where the factory purchased it from. Today
we know this material as NS4, or in American terms 5251. ISO
designation A1 MG2. .
