I've just added this camera to my collection and wondered if somebody could help with the maker. It's a 1/4 plate, with polished Mahogany or Teak, and Aluminium. It has many features that indicate Shew & Co, but has no makers badge on it. The "cut out" and stop, along the aluminium focus screen slide can be seen on the Xit range of Shew cameras, but I can't find that lens and shutter combination on. The leather carry handle has "Excelsior No 8", stamped into it, but that hasn't helped me. Below are some photos.
