Hawker Aircraft Roll Standards – A. STD. 828-216 and A. STD. 829-216

I’m looking for any information about the Hawker Aircraft roll standards of A. STD. 828-216 and A. STD. 829-216. These are the standards Hawker used to roll both the inner and outer booms for the wing and centre section spars of many of their prewar and Hurricane aircraft. Happy to purchase drawings of these standards.

Cheers!
