"All-brass Ornithologist's Telescope In Its Leather Sheath"
Eschenbach, does that mean anything to you? I'll leave it to you to research the history of this manufacturer of spotting scopes and binoculars established in Nuremberg. This spotting scope was certainly not intended for the navy, given that Nuremberg is rather surrounded by forests. I'm opting for a birdwatching at the end of the 19th century. Impeccable optics but given the magnification, it's not a question of trembling... A stand would be appropriate. Housed in its leather sheath, the deployed telescope measures 52 cm and 4 cm in diameter. PS if you want to use it at sea... it's suitable tooPS even if you're not looking for birds...
