I have had this precision tool for decades, always thinking I'd take time to figure out exactly what it is. Whether map reader, or a tool for something else, I have never seen another. Beautifully crafted precision folding tool, the handle is lathe-turned ivory, you can see the grain, and in fine condition. The 2 lens are without breaks or scratches, but seem to have dust within, and I suspect the one lease mount unscrews from the piece, though I have not forced it trying. It folds in thirds and has been well-protected in side the original leather clad case which is original. Dating mid-1800s, a pocket tool with 3/8" strong magnification lenses (2). Full measurements noted on the photos.
Very good to excellent condition for age and type, a fascinating little tool of some mystery. If you know what it is, please email to inform me and I'll annotate our listing. The lens needs to be cleaned in order to put it to use. As noted, it appears one side will unscrew, but it did not do so easily and I hesitate to force it. Handle is ivory, no losses.
IMPORTANT NOTE regarding antique tortoise shell or ivory: We are great supporters of protection for endangered species in our modern world. We never buy or sell anything 100 years or newer; we donate to anti-poaching organizations; we don't hunt; we conserve in ways that impact global warming (we're totally solar at home), knowing those measures also protect the animals in the wild today. We also recognize the vast cultural history we preserve with our care and reverence for these antique objects, and agree with CITES that objects over 100 years of age have nothing whatsoever to do with species depletion in our current world.
Our offering exceeds the age limitation of "more than 100 years of age", and is well within the exemption for CITES regulation. If imported, met the CITES regulation. This item will be handled and shipped from our Utah business, and is not available for shipment internationally, nor within the USA to California, NY, Nevada, Hawaii, New Jersey, Oregon, Washington if it contains ivory, sorry. Please see our small print for more details.
