Oh, I have one too since recently. Just not yet played very much on it.
For learning I can recommend this tutorial in 16 lectures:
Al Smith, Chord Solos for the 48 Chord Harmonica;
1989, Richfield Township, OH / Washington, DC, no ISBN known
Mine came with a CD, but this seems to be a home copy.
It seems to be only available antiquarianly / second hand.

This is a German website. But the seller is an american shop. I could not find their direct url. Maybe you can find it yourself, or maybe any other shop in the US.
And here you can read something about another tutorial book for the chord48 by Al Smith:

I have some more fine chord harmonicas beside the Hohner 48/384.
As there were
Suzuki SSCH-56 Chord (chromatic),
Easttop Mini Chord (similar to Tombo Pocket Chord, in fact a modified copy of the Tombo, diatonic),
Hohner Vineta No.4 (diatonic with Bass, several different major and minor keys).
If there is any interest in this, I can add some more reviews about them here every now and then.
