Hello! Inherited Dad's spear gun, some research shows that it is in demand, a Technisub Pulce 40. Includes original holder and spear. It has been sitting in the basement for probably two decades an I can't comment on whether it works. I see that it is also a Star wars collectible, but would love to see it go to a Scuba enthusiast. I am in the burbs of Chicago if you want to stop by and see it, or else I would ship with a Paypal payment. Email me if you are interested, I have not set a price as I have not seen a set like this.
