Has anyone ever done a survey of .22 trainers that were brought back from the "Great War" that had NO REAR SIGHTS? I ask this because I have seen several trainers of late that have been "brought back" that did NOT have rear sights. I think that the fact that that the rear sights are missing is strange, in that they don't just fall off. The Germans did a great job of not only soldering them on but also using a steel pin. I have a theory that maybe these rifles were actually sniper training rifles with scopes attached and that they were removed prior to being made available to the troops to "bring Back". What do you guys think ?
