You can get closer than that. Winchester unabashedly advertised the 1885 "Highwall" as the strong Sharps breechblock brought up to date with central hung hammer, self cocking.
Yep. I wanted to use a "modern" repeater to illustrate that some things that are borrowed aren't readily apparent on first inspection.
And we can fast-forward to Ruger's falling block single shots to see how "modern" some designs truly are...or aren't.
