| This is marked as catalog #721 and is marked "cut porro abbe" but we can't find this one in any of the catalogs we have. This appears to be 4 mirrors with blackened edges cemented together and polished to precision. Measures 32mm long x 21.5mm wide. Bottom and top are 21.5mm square. When looked through at close range you see the image in front of you and at either side the mirrored image of either side (left and right). May have been used as some sort of spinning intermittent prism. In great original condition. |
