This “thing” is about 4 feet long (you can see the water bottle just below it), is cast iron, rusted and HEAVY! It has what appear to be a trigger and sights. We found it last winter while clearing some brush at the Nature Park. Some have suggested that it’s a potato launcher ( no, too old, and heavy for the industrious 13 year old who might make one of these). We believe it may be a bazooka but cant figure out how if would have gotten into the Nature Park. Any ideas?
