Winchester 1895 "Tang Safety"

I just bought a new made Winchester 1895 Take-down in 405 Winchester - will be a nice match for my T/C Encore pistol in the same caliber. Unlike the Browning, the Winchester has a tang safety and rebound hammer, uses a two piece trigger. Which I'm told can be switched out for a conventional half-cock hammer and trigger of the 1886 Browning version. I've read up on the "how to" and found a hammer. I can't find a trigger. Does anyone have a source for a trigger?

Has anyone else given this a try? Has any practical advice to include "don't do it"?
