Up for sale is this beautiful W Watson & Sons Ltd 'Service' microscope. I bought this with the intention of learning how to use it but have never got around to it and have reluctantly decided to let it go. It is in lovely cosmetic condition for a c100 year old antique. I believe it is complete and working but am no expert on that so please do come and try before you buy if you can. I will post but would much prefer the buyer to collect.
