my brother found a conneticate valley arms hawkins 50 in a scrap yard. it was there a long time. i have cleaned it up and besides missing a rear sight and a ram rod guard its all there. i did make a ram rod the other was missing. the problem is there is a flat spring that goes between the trigger block and the hammer block that i cant figure out how to put in. any help or pictures would be great. its going to be a wall hanger but i would like it to work.
