Hello all! I am doing some research. I would like to know a bit about this US Divers Co. speargun. It belonged to my Grandfather. It's been in the attic for decades. I am neither a diver nor a spear fisher. I enjoy the water, I snorkel and I enjoy lazy day fishing. I am looking to find out a bit about this speargun's history and what it may be worth. I would like to sell it to someone who would appreciate it. I welcome any info. Thanks!
