Which template for organ ?

[MX]

Salut tout le monde !
Hi everybody !

I look forward a good lily template for the organ. I would like to 
produce such staves (see the following picture from the Bach 
Gesellschadt Edition) with :

1. A brace on the two first staves ;

2. The bar lines along the three staves.

I can do : 1. the brace on the three staves and the bar lines on the 
three staves. 2. the brace on the two manuale staves but a bar line on 
the two first staves and a different bar line ont the pedal staff.

Thanks in advance.

M.X.
