Gunbroker has a lot of garbage when it comes to German militaria, but not all there is bad. Occasionally, a bargain can be had for a genuine item. There are some dealers just as bad, with a mixture of authentic and reproduction items. As noted, don't buy anywhere unless you are totally convinced it's the real thing and know what you are doing. If not, don't buy, or seek the learned options of others BEFORE you buy, not after.
