What is the wall construction? (As there are several types that "are not

Of course.

It's a wall that *should be* solid, brick, rest of it was nice to drill
into.

when I came to fit hanrails in my father's house (Victorian) i found the
plaster could be up to 3cms thick. I had to use very long screws to get a
firm fixing.

I've found that often.
