There are better experts than me on this forum, but from what I know, it is probably either a standard GCF diatonic, or else a Steirische Harmonika (alpine) accordion. The difference is that the alpine diatonic will have a Gleichton (same-tone) button in the middle of the second and third rows, which will play the same note on the push and the pull of the bellows. If you don't have it yet, then you can ask the seller about this. Since the description calls it a "German Harmonika" I would guess it is an alpine. It looks like a really special instrument.
