Generally the 'Wender'-types are two harmonicas in one housing.
This means, that you can accommodate 4 chords in one instrument.
For in most popular music only 3 major chords are used -the cadenza-, we have the luxury to use one chord two times: At the C side drawing we get a Dominant 9th chord in G (without root). On the other side a clean G-chord is used as a blow chord without any modifications.
Well, just start over!
This harmonica does still fit every trouser pocket and you have nearly 3 octave chords available.
