I have a Daisy Powerline 777 with the Walther barrel, wooden grips, and adjustable rear sights. It is still in the original box with all the paper work. Gun is in great shape and shoots strong. This is out of my normal as I like shooting and collecting center fire and rim fire guns and don't know much about pellet guns. Is there a market for this gun and if so, what should I expect to get out of this gun when I sell it? Thanks!!!
