Hello I recently purchased a pair of very usable Wetzlar 10x50 ww2 binoculars, maybe slightly out if collimation, I'm more of a military binocular collector but this forum has provided the answer for me in the past 😀. They are 'dienstglas ' or service glass binos and are marked H/6400, this means they should have a ranging graticule in the right lens...they do not have this at all, the screws are all complete but evidence of someone having taken them apart is there. The leatherette is slightly brown in colour, they are a nice pair, I own others like them I'm just wondering how/why the graticule had been removed or horror of horrors they are not a correct pair of ww2 german optics. Any info would be most welcome, I attach photos.
