My Dad has had a telescope since he was a kid. It is handheld, sort of like a spyglass. The barrel became dented somewhere along the way and I would like to replace the barrel so that it may function again. The endpiece holds the lens on the barrel. The barrel is approximately 50 mm across and 30cm or a foot long.
The telescope has no makers mark on it so I don't know where to start looking for spare parts. I think if I find the right diameter of tube that I can fix it though. Thanks for any help with this matter.
