I had an idea for a Vampire: the Masquerade character. In life, he was born around 250 BC in Rome, he fought in the Second Punic War, and when he was turned into a Vampire, he just held onto the weapons he was issued. Over the next 2200 years, he'd insist on continuing to maintain and use his old Roman kit under the justification of "if it was good enough for Cannae, it's good enough for now goddammit."

Is this realistic? Could a weapon continue to be serviceable across millennia if its immortal owner were diligent about keeping it maintained?
