Harmonica range

["Scorcher" <s_c_o_r_c_h_e_r@xxxxxxx>]

Is there a resource on the www that details the range (scale, notes,
tuning) of "other" types of harmonicas?
I'm pretty familiar with most diatonics (10, 12, 14 hole) and
chromatics (12, 14, 16 hole), but I'm looking for
more detailed information on Tremolos, Octaves, and "orchestral"
harmonicas.

I haven't found the information I'm looking for in any of the "usual"
places; Coast2Coast, FR Farrell, HohnerUSA, HarpOn, Mike Will's page,
etc....

Anyone?
