thanks
the story of this gun is something confuse

1. number shows the gun was made in 1895
2. the trigger wasnt available before 1901
3. the steel barrel was available but is maybe a replacment from the 1920 years
4. the stock isnt original but nobody can tell me if the beavertail forend looks like a original forend later replaced from fulton

what I read about the single trigger isnt amusing, a gunmaker's hour cost here 60 euro +.
I think he need the first hour to understand how the trigger works. have the gun again in my hands in two weeks und will look for the things you note + barrel length, chamber length etc.
here are two pics I dont use before because of quality, maybe it helps.
