I remeber as a child, I too got an Indian Warpath set. Stick bow, plastic knife, and feathered head band. I took out one morning, looking for settlers, and low and behold, a kid from around the block, was out looking for Injuns. He had a coonskin hat, cap musket, and the ever popular plastic knife.
We became good friends from that point on, but the coincidence, of that chance meeting, was quite unique.
Kudos to your valuable find.
