Lovely silver plated OOW telescope, standard design, made by Ross, possibly in the early 1900’s. Optics are perfect, but the original leather cover has the stitching beginning to part, as it has shrunk.

The engraving on the first and only draw says Ross London, with the production number 29155. Then on the opposite side the engraving says “Sold by Seagrove & Co Portsea”. The eyepiece cover and the splash shield are both coated with what seems to be the original lacquer. There are no noticeable bangs or dents. All screw threads run smoothly, so it is easy to both use and clean.

Lt George Edward Washer was a resident of Dunedin, New Zealand, but joined up in 1916, according to RNR war records, and was demobilised in 1919.

GB Telescope Collector

I first started using a telescope in the 60s, to identify aeroplanes arriving at Yeadon airport, in Yorkshire. Then I started to collect and restore vintage brass scopes in the 1990s. The collection boomed later, in the early days of the internet, rising to around 300 in number. Since then I have made a lot of friends via the internet, advising them on how to identify, date or repair their scopes. At the age of 74 I need to disperse these wonderful bits of engineering history, because they still work today as well as they did 200+ years ago! That is the fascination....Some of my collection have already been sold to collectors spread around, in the UK, USA, Ireland, Israel, France and Germany. Several have been returned to the UK descendants of the people who made them, or relatives of their previous owners, because they found the stories on my website. Now the collection needs to be dispersed more systematically. If you are looking for a specific telescope, just ask, maybe I have one! If you want better pictures of the telescopes shown here, these can be emailed. Nick Denbow, based in Alresford, Hampshire: contact via email on
