Mother of Pearl Lorraine of Paris Binoculars/Opera Glasses

This Mother of Pearl - Lorraine of Paris Binoculars/Opera Glasses has been in our family for many years. We were curious about when they may have made made as the leather case they have been in is old, and worn with age. When I look up Lorraine of Paris - the other thing that comes back is LeMaire of Paris but as you can tell from the picture it says Lorraine. Thanks for any help you can give me!
