Does anyone have any idea how much one of these guns is worth? It still works like it did then, in used but good condition, and still in box. Also, is it better to sell on eBay or some online bidding, or fix the price and sell it that way? Thanks for your input!:) [img size=154]https://kovels.com/media/kunena/attachments/legacy/images/agent0cameragun1966_Mattel.jpg[/img]
