The 11 in Birmingham goes up to 11E doesn't it? So the Outer Circle can
be divided into sectors?

If you want suffix letters, go to Chennai (Madras) in India. Many
numbers seem to have all possible suffix letters from A to Z. And the
18A has Ashok Leyland Titan rear platform double-deckers. It's pretty
confusing for visitors, though.
