was an American optical instrument and laboratory supply firm formed by H.S. Williams and N.H. Brown at 918 Chestnut Street, Philadelphia, Pennsylvania.
They operated from the late 1800’s to the very early 1900’s.
Their extensive catalogue included laboratory
and medical
instruments
, chemicals and
accessories
.  They also offered
microscopes, binoculars, magic lanterns,
and many other types of scientific instruments.
It is not likely that the
y
made
any of the items in their catalogs but were primarily suppliers.  Both the instrument and the card inside the box are identified by the maker.  The instrument No. 106 also matches the card.  The card has a very faint date stamp of  AUG  12 190_.  The tester looks like it was used very infrequently since the nickel-plated finish is excellent and the 4 glass shades are perfect.  The tester is 4"L x 1-3/4" in dia.  It comes in its original leather covered, felt-lined, wooden storage box.  The nickel-plated closure latch works as it should.  The box has wear from use (see pics).  A RARE instrument that you never see for auction on eBay !!
