Raimey,
That gun was about next to last in importance in the Emil Flues story. His family got that gun by default when he passed. The reason I say this is because all throughout his indentured servant days (for lack of a better word), he took special pride in producing master works of art (engraved by Kornbrath) that he sent to family members who resided mainly on the west coast. One by one, all were stolen eventually...and that's probably why we don't see many to this day...The gun pictured above is one of the massed produced Flues guns of the twenties. Most collectors are not even aware that he attempted to mass produce double shotguns while living here in Buffalo NY.
Many of his master works are sidelocks though not all....it seems that there is just something about Kornbrath engraved guns that drives people to do unethical things that they wouldn't ordinarily do
