It's beyond understanding. One of my interests is Remington 30-S rifles, considering the small number of them built, the number of disasters out there is amazing. Or maybe just too many disasters drifted into my orbit. Some were terribly butchered, others, I think the only original part left was the receiver. It's like they were bought for parts, cannibalized except for the receiver and sold off, and then those parts were replaced with old surplus, a cheap stock installed, and then that was sold off. I think unless you were around when some monkey got his paws on something, and watched him work his magic, it will remain a mystery.
