Erich yes semi-Girling is strictly correct but more effort to say and write!
All I can say is take a look at a modern brake drum and compare it with an A7 - they are tragically thin to start with and skimming only makes them thinner. I've worked on cars where the stiffening band added to a brake drum to limit ovality was more than the mass of an entire A7 drum!
Bravo to Tony for sorting out some new ones. If anything like his past stock I'm sure they are a good buy.
