looking for 1917 trunnion and end cap info

What exactly are you wanting to know? I have taken a half a dozen of them apart to raise dents from the waterjacket. Even though no one has a pic, if you ask your question someone might be able to give you some helpful advice beforueyou "fake" something up

I currently have the endcap off of one I am working on. I can get you pics of that, however I dont remove the trunion end usually. These things are soldered so I only remove the necessecary end to get in and raise the dents. I will put up some pics later on.
