I received the book "Trapdoor Springfield" today that I purchased from MO member gunscrewguy. After looking through it--I verified what I suspected--this rifle is probably a Bannerman special. A rifle reconstituted by a company that sold surplus military items back in the early 1900s. This is a rifle made up of surplus parts--a fully functional firearm made up of odds and ends from junked Trapdoors. My 1878 rifle has a 1882 era ramrod and also a late 1870s Trapdoor carbine rear sight--not the one made for the longer rifle model. That is OK by me! I am having fun with this old timer!
