The repro rod is something a former owner inserted. The correct rod would have been retained by a spoon and threaded into a steel retainer (CW style).
Reviewing the Hotchkiss rifle and carbine photos (pages 256-264) in Dick Hosmer's new book, "More 45-70 Springfields 1873-1893", and reviewing the facts
listed above, it appears this rifle is a Remington prototype rifle made for US Navy evaluation.
