Yep. They were really cheapo drums back in the 60's. Kids everywhere were playing them in garage bands. Nobody could get their parents to spring for a real pro set. When some kid would actually get a real Ludwig or Gretsch set, we would all go over to his house and droll over them. Of course, he couldn't play them, but his parents were rich....Stencil brand import. The Zim is part of someone's name as is Gar, (Garfield.) They imported and distributed musical instruments in the 60s and 70s. I believe that they were made by STAR, which is Tama now.
