I want to print bar numbers every 5 measures

[Kim Shrier]

Hello,

I must be missing something obvious.  I have been trying to get lilypond
2.9.14 to print bar numbers every 5 measures instead of at the beginning
of each line.  I have read the manual and looked at the example in
bar-number-every-five-reset.ly but everything I have tried either has no
effect or makes bar numbers disappear entirely.

Below is the source of the song I am typesetting.  I would like bar  
numbers
to show above the top staff every 5 measures.  Any help would be  
appreciated.

\include "treble-one.ly"
\include "treble-two.ly"
\include "tenor-one.ly"
\include "tenor-two.ly"
\include "bass-one.ly"
\include "bass-two.ly"

\header{
    title = "6 part consort music"
}

\paper {
    #(set-paper-size "letter")
}

\score {
    \new StaffGroup \relative <<
        \new Staff {
            \tempo 2=50
            \TrebleOne
        }
        \new Staff { \TrebleTwo }
        \new Staff { \TenorOne }
        \new Staff { \TenorTwo }
        \new Staff { \BassOne }
        \new Staff { \BassTwo }
    >>

    \layout {
        \context {
            \Score
            \override BarNumber #'padding = #3
            \override RehearsalMark #'padding = #2
            skipBars = ##t
        }
        \context {
            \Staff
            \consists Ambitus_engraver
        }
    }

    \midi {
        \tempo 2=50
    }
}

\version "2.9.14"
