There's 3 Engineering made target dummies in Classic. You could have found this out quite easily if you bothered to look. Search box: "target dummy"
http://db.vanillagaming.org/?search=target+dummyThe problem is that, last I checked, they don't work on Nost. When I last used them, they would produce threat to any mobs, and never became a lootable corpse. Even if you walk up to a mob you did nothing against and drop the dummy, the mob just ignores it and goes for you. No threat, no return loot, no point. If you're hoping to get fused wirings, stick to making Goblin Rocket Boots, because these work as originally intended. When they expode they return loot, and I've gotten a number of wires from it. The looted wire actually profits you through the explosion, but rarely occurs.
