VTG Sans & Streiffe No. 508 500x Quadruple Turret Microscope w/ Dissecting Kit.  This microscope is provided with the magnification powers of 100x,200, 300x, and 500x by revolving 4 nose-pieces and also a complete set of dissecting tools.   This I believe is from the 50's.  The set has several bottles of various liquid aids but the bottles are all empty due to age.  The other tools appear to all be in great shape.  The strap on the carrying case is broken.  Make a nice addition to your collection.
