Antique Opera Glasses PATENT

This is a patented antique opera glass.
Regarding the lenses, there are about two small scratches on the larger lens.
No scratches were found on the smaller lenses, but there are some small spots that look like dirt.
For reference, photos 15 and 16 are uploaded. The smaller lenses seem to be removable by turning the black metal cover. One side turns by hand, but the other side, where many screw threads are visible, would not turn by hand, so I left it as is without forcing it.
As this is an old item, please purchase with understanding.

This product is strictly a used item, and depending on the product, dirt, scratches, etc. may be difficult to see in the images. I have checked the item for listing, but I may overlook some areas, so please understand. Please be sure to check the condition of the product and the comment section.
