Over the years since Harbin's death, different models of Zig-Zag have been produced in variations to eliminate the boxy roller curain boxes.
Not too long ago (in geographic time) I acquired a model where the leatherette curtains are gravity fed and controlled by internal guide rods.
I am not sure of builder of this model -- but I believe it originated in England and would like some info, Do not know if Brooks ever did this (Peat?) or if it may be a Ron McMillan version.
Any ideas on provinance -- it came frm Florida to Arizona....
