[Harp-L] Highlander Scottish Celtic Double Sided Tremolo Harmonica

[Jim Hanks <jhanks@xxxxxxxxxxxxx>]

I don't have any tremolo harps, but this one caught my eye:

Has anybody tried this? My first question is: how does this work? There 
are 40 holes, but they're all blow, right? Are all the bottom holes a 
low D to get the bagpipe drone? Or is it just a bagpipe scale somehow 
and there isn't a drone?
