In the trench in the arch of the frame there was usally some sort of sticker. Well there was on some of the later one piece tank Victas i have seen.
Also seen one or two with stickers on the tank. I would imagine they would not last tooo long there.
Model is not really relavant. If you are looking to sell it just call it a Victa Power Torque, someone will buy it and be happy. It does not detract from the value. I sold a bitsa, not as neat looking as that for $123 at auction on eBay without a catcher. Prior to that i had got $140 for a Commando and $120 for another named model Victa.
