Nevermind! Looks like you got it handled!
As far as the shotgun, I am no expert as to what the camo pattern is. But, if it is an unported 835, it is older, probably from the early mid 90s. Someone here will know more than me about the details of when it was made.
But as far as the performance of the 835, I have had one since 1998 and I love it. It is a turkey killing machine! Depending on what you are trading, it should be a good deal.
