Ithaca doubles certainly were not popular among Pigeon shooters. They very rarely appear in the listings of guns used at the Grand American Handicap at live birds 1893 to 1902. The boys and girls at Fall Creek certainly remedied that at clay targets with their Knick SBT!!
Actually after Ithaca abandoned the double gun field this guy won the World Shoot at Madrid, Spain --
with an NID.
Doc. Drew -- the first picture you show calling them
a Remington Model of 1894 Hammerless C grade with "Washington N 3 B.P.". Within the scrolls are tiny rectangles; not crosses or stars
appears to actually be a set of Parker Bros. barrels
