Hello, Kent.  I've no idea what you mean by "20/55", but aside from
that, you should try to locate a copy of The Contemporary American
Organ by William Barnes, any edition.  He shows interior views of many
windchests by many different builders.  My own choice would be to build
chests as did Robert-Morton, Wangerin, and Kilgen, all well-respected
builders.  These were pouch chests, so wouldn't make use of your square
pneumatics, but they are comparatively simple to build.  Good luck with
a great project!
