I recently purchased an old colt D.A. 38 and a springfield 1898, my only problem is that when I was cleaning the guns off last night I realized it didn't have the big plated side trapdoor loading part that I've seen in a lot of pictures. I don't know much about these rifles so I'm not sure whether they made them without that or I got some kind of a reproduction fake?? Any info on this would be a huge help because it's been driving me nuts!
