I have inherited this gun. it is nickel plated revolver and a top break 7 shot. It is the "old model" and it need some parts. I ordered a trigger spring for it which is the flat style spring. My gun did not have one when i got it. I ordered the part along with a schematic from Numrich but the schematic is the for a .38 and apparently they dont have a schematic for the old 7 shot .22. How in the heck does the trigger spring go in???? I have set at the desk and played with it for hours. Any pics would be great..... I am lost totally. I do have a link of the trigger spring.
