18" BRASS TELESCOPE NEW WITH CASE
This is a very nice display piece as well as a great work-
ing telescope. We replaced the original poor quality
objective lens with a new AR coated achromat, and this
provides excellent views! We believe it is about 12x.
Objective is 36mm diameter. Overall telescope length
is 18". The length when retracted is 8-1/8". The brass
on the barrel is covered with real leather (very nice
when its really cold or really hot!). The wooden case is lined with felt and
measures 8-1/4" x 3-1/8" x 3". On the top of the case is a brass anchor
logo, similar to that of the Navy. Unused. Shipping weight is 3.5 pounds.
