I have been given an old pair of Fujinon Binoculars 40 x 150 1.7 degrees.
I can not get them to focus. Is there anyway I can fix this or will I have to send them off to get repaired?
They are very old binoculars!

Hi Wigs,
Boy, I would love to have a pair like that. Never seen any like them before.
A couple of questions. Do the eyepieces turn freely? What are the markings on them? It may be that you are trying to focus too close. IF the markings are +/- 10 diopter, you may get a close focus of 150 or so meters, +/- 20d, about 80 meters. The eyepieces may not be marked and turn several revolutions to get to a closer focus.
A picture may be helpful for those who are familiar with these.
