hello-I have a Kolb new baby 6 shot 22 short cal. revolver with what is called a "Z" bar to open this top breaking pistol.What I need is an exploded view of this little pistol so I can order parts-you see,this pistol was given to me after about a dozen people took it apart and lost parts so I need to see what all is missing so that I can order the parts (if they are available) to put this nice old little pistol in working order.Any help at all would be appreciated...Thanks!!!
