The bell character is control-g so you should be able to get it the
same way as your escape character.  In your case using ctrl-v ctrl-g
and you should have a literal control-g in the input.

As a matter of style I frequently just use '.' to match any character
there and ignore the fact that it is possible to match something
else.  In that way I don't have to worry about cutting and pasting the
code and problems that might arise.

sed '
        /^\[-- Autoview using .* --]$/d
        /^.][0-9;]*.\[-- Autoview using .* --]$/d
        /^\[-- Attachment .* --]$/d
        /^.][0-9;]*.\[-- Attachment .* --]$/d
        /^\[-- Type: .* --]$/d
        /^.][0-9;]*.\[-- Type: .* --]$/d
'
