Cool factor of 10/10.
I wondered something though (and you don't have to answer this)... Are you trying to establish it's uniqueness/monetary value for insurance purposes? I'm married into an insurance family, and have been reminded a number of times that I should have detailed records of what I have, it's value, etc. And BELIEVE me...there is nothing in my collection that comes close to what I suspect the value of that gun is. I doubt all of them together would!
