Hey there, first I would like to thank everyone for the wealth of information here as I continue to learn about my 1-pipe steam system. After reading the wall I decided to look into my main venting. I have included some photos of my main vent and am hoping for some help in identification (sorry for the angle, it is wedged pretty far in a corner). Regardless, I am under the impression moving to something like a Gorton #2 would be beneficial. It would also give me the opportunity to pipe the vent a little more effectively if needed, since I would need to build an antler to fit it. I would appreciate any input. Thanks!
