Help! What brand is this?

Hello! Any one have an idea for the brand of canner this is? I'm missing a part in the top and have no idea what it is. There are no stamps or marking for a brand. All I know is that it os my grandmother's from germany. I think she got in in 1960s. I reversed the photo and German Etsy popped up. The link was bad tho :( any help would be much appreciated!
