A good simple microscope with 2 Lieberkuhned objectives (beads intact) and exhibiting aquatic (side to side) motion/focussing via a round rotating rod inside of the upright. The stage inserts by means of a chamfered ear and the other ear is for the hinged stage forceps. Stage insert is a concave glass with a tiny edge chip (no B/W ivory disc). The stem is cylindrical with a boxed out area with hole for the mirror stem. The 2 inch, single sided mirror has 98% original silvering and the stem has be slotted to apply tension once inserted. The 5 x4 x 1 inch black sharkskin case is near flawless with both ornate, eared hooks intact. The brass ferrule to the lid is held down by three (3) steel screws. The interior is Georgian green velvet with no issues. 

Although well used (not abused), this instrument has very good optics and is easy to use. Pocket sized for the gentleman naturalist. The Ellis/Tremblay aquatic microscope was invented c.1755 and marketed heavily by Cuff, Dollond, etc.
