Very little as sweet or as accurate as a NS Target in 44 Special/Russian (they amre usually dual marked and will shoot either round). I have an early model and a very late, 1930s NS Target in 44 and they are great guns. Too labor intensive to be resurrected today. The closeset your are going to get to guns from this era are the S&W Classic series. But even there, Smith didn't try to re- introduce their premier revolver of that era, the New Century, aka Triple Lock. I spoke to a Smith insider about that, and he said just too labor intensive and they would essentially have to be hand built and fitted.
I hamve been a NS collector (and an early Smith collector) by entire adult life. The centerpiece of my collection are these guns, including a cased set of consecutive numbered and lettered NS Targets in 455 delivered to London in 1915 as well as a 7.5" Triple Lock Target with factory pearl grips, mint and very rare. I love them and consider myself their custodian until I pass on.
Enjoy what you can find, it is a bygone era. Dave
