This is a very unusual pair of early prism binoculars.  Instead of using the more common-Porro prism assembly, this pair of binoculars uses an in-plane prism assembly.  The prism assembly makes use of a roof prism.  The binoculars also indicate "Tourox 8X" with a serial number of 13910.  The binoculars come with a leather case embossed with the owners initials "E. M."
