An object can be old without being famous or fine.
A tool is recut into another trade. A blade is re-edged and rehandled. A campaign trunk holds a cheap medal beside repair receipts and an obsolete service paper. What survives is rarely pristine; it is what each generation found worth mending.
Family legend can be true without becoming public history. A household may preserve one sentence about a strike, crossing, regiment, rescue, or disgrace that never entered a textbook. That does not mean no paper survived somewhere.
If an old weapon, shield, tool, letter, garment, or instrument belongs in your story, say what was replaced, who last repaired it, and why your character still carries it. Bring any answer that adds shared history as a session-zero proposal.
