The top of the lenses reaches just above the top of one's head.

We have been unable to locate information. Maybe a prototype? Happy to post information anyone wants to share about the binoculars .

The binoculars are in working order and the lenses are clear.

All the moving parts move smoothly. The leather strap is complete.
