I know you said NOS or very nice core. I thought someone would have one for you by now. I've got one that has perfect slide rails but a bit of surface rust inside. If you soda blasted it, it would probably be pretty nice, but might not be as nice as you're looking for. Let me know if you want pictures of it.
