Very Early Antique Watson & Son Bar-limb Brass Microscope c1875 with Fitted Case
USD 382.27
Its design is of the bar-limb form which was very popular in the Victorian period, being first introduced by Andrew Ross in the 1840s and then rapidly copied by many other makers. Whilst the firm of William Watson was founded in 1837, they didn't manufacture microscopes in large numbers until the 1870s, so this is an early example and it's actually the earliest serial number Watson that I've owned in nearly 40 years.
