British Admiralty Pattern
Single Draw Marine Telescope
Ca 1875
This is one of the Admiralty designs which makes it special. It is a quite large, high quality, British Admiralty pattern, single draw telescope designed specifically for marine use. It is in
fine condition for its age and use at sea. The scope has an unusual very small mark of an anchor and the words “Try Me”.
It is in full working order with clear optics focusing out considerably when fully extended. The center barrel
is made of mahogany, 14 3/4″ long, which is covered in the center with a woven brown painted 4-strand line.
Areas of the woven cover show ware. Fully extended the telescope measures 37″. The lenses are uncoated and clear. The telescope was likely made in the last quarter of the 19th Century.
DIMENSIONS:
It measures 21″ closed and 37” extended. The objective lens is 40mm in diameter. The exit pupil
diameter is 12.75 mm. Weighs a heavy 3 lbs 7 oz.
CONDITION:
Admiralty pattern, single-draw telescope of brass or copper. The barrel’s center section is covered in brown painted
duck as described the paragraph 1. All the brass is free of larger dents which is remarkable. There are only a few small ones.
The large 40 mm objective lens and the ocular lens are uncoated. Both dust covers are present and in perfect condition. The
focus is sharp and clear. There is a sliding sun shield to reduce glare at sea. Both lenses are free of fungus. Overall, it
is a fine example of a genuine antique marine telescope. It will be a good investment.
