I'll say this again....I'm only interested in figuring out a consensus price for the piece as it is currently.
If I'm able to acquire it, then there is only one path....restoration to a proper 10 bore shotgun, as Herr Lindner intended. No other path will be considered. If you want to have a discussion about the wisdom of that kind of approach, please start your own thread.
I personally think it's nuts that people spend years and many $1000's on high condition low grade American guns. They were hastily made in large factories to hit a price point. But today people spend more on those than they do finely made mid quality English guns. But I don't get involved in those discussions and I don't tell people they are nuts to do so. To each their own.
