My Dad recently passed away, and we trying to understand whether this Parker Brothers side by side is a keeper. I sent for a letter. Mark was kind enough to share that the only record is an 1882 return to repair the lock and get the right barrel to shoot better. We've never shot it due to concerns about modern shells in the Damascus steel barrels.
I think this link will take you to a whole bunch of photos.
