Informations needed for a Winchester 1890 third version|Winchester .22 Rim Fire|Forum|Winchester Collector

Hello!

I’m from France and just bought an elegant old lady and would like to have informations about. Please excuse my english or my lack of knowledge!

What I know:

-1890 third model in .22 short , serial numbers are the same and lead to 1913

-there are a lot of english graffitis on it… absolutely no taste in there! British proof marks tell that the 90 was there before 1925 (London lion+ letter mark), Birmingham stamps are from post 1954 (crown+BNP), 1961(cross swords+MB3) and 1984 to 1989 (6.5 tons per square inch). From what I know it probably has been used to form the trainee of the english army. So maybe the gun is a little tired?

-on the stock there’s an incription of “Lincoln Jeffries” and his “trademark” (a little man who aim at something). Apparently he was a gunmaker in Birmingham, mainly in air rifles. Maybe his society imported the 90? Now they produce pellets (Marksman)

-the “slide action/pump” mechanism seems to me a little hard. Two clues about it: I suspect too many frictions on the breech block and mainly I think that the hammer spring is not the right one. I looked on the pump side and it seems to work well.

What I would like to know:

-Among the **** *** **** *** *** “proof marks” on it, there’s one who say “22S 40g” (I think). Maybe it is 408? Maybe something else I can’t say. But if it is “40g”, it means 40g like the .22 LR. From what i know the .22S is between 27 and 29g so I don’t understand what it is about.

-Can anyone tell me if the hammer spring is the right one? I can try to do a better picture if necessary

-How is the gun for you? Good enough to shoot .22S once a week or just good to be collected?

-I put Ballistol on it (never will again, it stinks like vomit…), can I try to use a gun degreaser to clean it a lot or should I leave it in this state otherwise it would ruins the browning?

Here are some pictures. Thank you!
