Most interesting as I did suspect a Belgian origin but not an Auguste Francotte tubeset. Right off, I can't remember to whom the crown over "MG Bte" belongs but we have seen it recently(Francotte retailed in Paris) and maybe Peter or Marc remembers. Is there any name like Charles Daly or the like atop the top rib?
