I got these along with some other German WW1 items. The item with the swastika seems to be a clip of some sort. When you pinch it, there are teeth on the opposite end that grab onto something. The other items seems to be a oiler or liquor flask of sorts. You fill with a liquid or oil, then when you squeeze the fluid goes up the tube and out the little boys private area making it as he is urinating. It says GERMANY along the ridge. Any help is greatly appreciated, thank you!
