These ingenious antique binoculars were crafted in Bordeaux France by the Crosti  company. 
 
We call them ingenious due to the fact that they have three various lenses built in to the optical lenses.  
By spinning a wheel on the side of the lenses you can alternate them between Theatre lenses, Marine lenses and campagne lenses.
 
The eye holes and the button on the side of the binoculars are beautifully decorated with bees and the company name.
 
These are in great condition for their age. The lenses do need a clean inside (which can be done by unscrewing the binoculars to get inside) and one of the lenses is cracked on the 'Theatre' lense option. We have tried to photograph this as best possible to show the wear.
