Hi! My passion for birding has recently been rekindled and a member of the family has dug out my grandfather's binoculars. Lizars 130 is inscribed on the binoculars. There are also some numbers on the binoculars: 57, 72 and 8x26. I daren't guess how old they are, but they have been well looked after. In the brown leather case is a sticker which says J Lizars Ltd. Opticians and Photographic Dealers, 101 - 107 Buchanan Street, Glasgow. I don't really have the first clue about binoculars but I'm quite happy to use these for birding, especially because of the sentimental value of them, but I was just wondering if anyone might be able to shed any light on this particular make for me?
