I have one of those books and Joe is right, the information is there: 382 ± 1 mm for 220 SEB/C. Obviously this is still narrower than yours so that's a little puzzling.
The book states 375 mm ± 1 mm for 220 B, SB, SEB 1st version
The book is not the BBB, it's much smaller and contains only specifications, not procedures.
