Does anyone know what the bass side reed layout is on cajun accordions? I'm missing a reed and would like to order a replacement from Hohner (it's an old John Hebert with Hohner reeds..in C). I'm thinking it's the following but don't want to assume too much:

Bass.....x C c

Chords...e c g

where "x" is the reed I'm missing.

Are there then three bass notes, in this case one low C/G and two high c/g's? And for future reference, are the reeds which constitute the chords e/b c/g g/d, or are they configured otherwise? I ask because on Hohner three-rows they're apparently d/e b/c g/g, which isn't illogical but not what I would've expected.
