• This frame looks to be made in the early Edwardian period
  
  although the style was made from the last part of the
  
  18th century. It is known as the Riding Bow frame as the
  
  cable temples would help keep the frame on when riding a
  
  horse. Of course, when cars became popular after WW1,
  
  this style became less necessary and gradually disappeared.
  
  We've seen this shape in numerous catalogues up until the
  
  1920s sold as both frames and with sun lenses. There is
  
  nothing to signify what the metal is (ie a mark for silver or
  
  a brand-name), so from an early catalogue in our collection
  
  it could be 'white metal; 'nickel plated': 'steel nickel plated'
  
  or maybe Alumnico (aluminium). And it was obviously a
  
  success as look at it here: 100 years on and it looks fantastic.
  
  The lenses are the flat type made up until the 1940's, here in
  
  a pale colour but with excellent uv protection. We think the
  
  colour may be the lightest of the Euphos tints available then
  
  - a yellow-green, that came out in 1907. NB: these frames
  
  were meant to be small as they were intended to frame the
  
  eyes, not the face as frames do today. But it is a size that
  
  would fit men or women.
