Recently I bought a Winchester 94 made in 1971. Unfortunately the two tiny little screws fitting the holes for holding a Lyman receiver sight are missing. These screws are No. 26 in the picture of the link below:
What size do these screws have? Probably I can buy them here in Germany although they will not be of metric sice but I can get them from a hardware store specialized in rare tools and replacement parts. Buying and shipping these screws from overseas to Germany will be to expensive.
