A superb ALL BRASS German microscope. All original and undamaged. This scientific instrument comes with the original serial number card ( # 26224 ) , which was issued with the microscope in 1893. The card also shows that it came with 2 OCULARS as opposed to three, the number # 3 size and # 7 size. So it isn't missing any oculars, it just came with 2 as proven by the original serial card. On the back of the card it was signed by three users, one person in 1894, one in 1902 and another in 1906. Comes with its' original box & KEY ! The box has an age - drying crack down the back, however the box is still strong and sturdy. Also included with this package are 2 barlow lenses of 6X and 10X . There is also an accessory box with glassplates , etc. All brass instruments are very desirable. Not too long afterwards , microscopes were made in brass, but were made with iron bases. Then brass was dropped altogether by the 1920's. A true classic piece. There are 10 pictures total....so keep scolling to see all the shots. Offers considered.
