Take it to a SxS gunsmith and determine if it is shootable. If so, fire a few low pressure shell in honor of the man whose sweat polished the wood and smoothed the steel.
Place it in a place of honor so that any that sees it can ask and hear the history and know the respect that a family relic can generate.
We are only products of those that made our lives what they are. To hold, use, cherish something that a forebare used to make life possible for yourself is treasure beyond understanding.
Best,
John
