Hi Claudio, Nice badge! I have seen the basic one like mine, then a version with oakleaves, and now with oakleaves and "25" ... For the bigger one with the crown, I am going to go out on a limb and doubt Nimmerguts catagory. There are the established membership pins (I assume newbie, 10 year and 25 year) and I don see the big badge simply being there as a unusual or unofficial Association badge. As it came out of a Generals group (Leib Regt officer during the war) I am guessing that it is some kind of Merit badge or distinction within the association? I have been looking for Leib Regiment items for quite a few years and this is the only one I have seen, so I would go 2-3 times what Nimmergut quotes ;-) The Leib Regt association actually predates WW1, so not Reichswehr time. I have to look but I think I have association membership certificates from 1905-06. If you brother wants to trade... ;-)
