Hello Dugas,
I found better: I guess your instrument is a Weltmeister Stella?
For the 32 basses the standard (German and Italian) is the following:
Four bass columns (left hand, from the bellows):
fundamental basses,
major chords,
minor chords,
dominant 7th chords.
Fundamental basses (from bottom to top):
E flat - B flat - F - C - G - Re - A - E
Hoping to have been useful to you.
