I wonder what happened, a older gentleman gave up hunting put it away and through the years of people moving this cased masterpiece around, not having the slightest idea of what was inside, throwing it, banging it against walls and stairways, storing it under heavy furniture or something keeping it in a moist environment then when finally someone said, "I wonder what this is", finally opened the case saw what it was and fell over dead with a heart attack??
All the best
