Apologies for the lack of some information - I was in a rush. Look on eBay, they are titled.... Vintage WW1 binoculars with case. Item number is.... 271633035437... one of the objective lenses is missing, but this may put off others from bidding. It wouldn't be too difficult to find a similar pair of binoculars to effect a repair.
