In A Nutshell Antiques and Interiors has dated this piece to the 1930s.
The eyepiece tube is marked "Britannic. Made in England". Closed, the telescope measures approximately 11 1/2" but fully extended is measures 23". It is approximately 2" wide.

The telescope comes with its original protective leather end caps and adjustable carrying strap.
The telescope is in good original condition. It has been lightly cleaned and displays beautifully. It has clearly been well looked after and the tubes are in excellent order with no major dinks or dents and a smooth but firm draw action. The optics through the telescope are good and the lenses are undamaged and generally clean. Please just bear in mind the telescope is 100 years old and the lenses will not be like new. The leather cases are all in good condition with a nice aged patina. There is some wear on the straps but no major breaks or damages.
The best description comes from the photos so please look at them all carefully and if you have any questions at all please ask.
