This came out of my parents' warehouse. There aren't many heads, perhaps because they were stored separately. I don't know much about them, so I don't know what series they're from, but I think they're about 30 years old. Everything in the photos is included. The condition seems pretty good to me, but I'm not an expert. Please refrain from purchasing if you are overly concerned about condition. I don't know the market price at all, so I'm listing them at a high price, but price negotiations are welcome. Thank you.
