I was finally gifted a family heirloom, a Remington Rolling Block that hung over the mirror in the family bar and restaurant for decades. I'm pretty sure it's a 43 Spanish, but was unable to find a seemingly easy to use site to ID the rifle in the 34.7 gazillion hits google gave me. Any favorites someone would like to suggest.
ETA, it's full military with stacking stud and cleaning rod. Dated 1888. A #1 right?
