This is a Watson & Son microscope circa 1870's everything is original,in
In 1883, the name of the company was changed to W. Watson & Sons
The hight is 43cm and the hand made wooden box is 44cm x 24cm x 21cm.
This is part of an email sent to me from a valuer :-
"The firm signed instruments as "William Watson" 1937-1862, "W. Watson & Son" 1862-1882, "W. Watson & Sons" 1882-1908, and "W. Watson & Sons, LTD" 1908-1957 each at the address on your microscope. My guess is that given the lack of serial number and the style of the microscope, it dates in the 1870s."
