Hi, I have got a "telescope" from the local market, but I don't know if this is a telescope or not, because this one doesn't extend and pull back as other telescopes do, I am posting some pics in here, so if anyone knows what this really is, please would you leave your comments here, many thanks!
You might want to post this over in the spotting scope forum...or ask a moderator to move it for you.
Looks like it might have been a permanent-mount scope on a ship, plus I seem to barely be able to make out the MOD broadarrow at the bottom of one of your pictures. I think you'll have a lot better luck posting on a military items forum, or even someplace like
