I have had a set of plans for a year and a half now. Recently I picked up a previously started project with no paperwork. I know fun times haha. So now that I have preserved the tubing with some zinc phosphate. I have had a chance to see what I got. Station 85-137 seems to be wrong. There is a station at 116 but not at 111. Seems like station 99 was removed and a long diagonal tube runs straight down to 116 then back up to 137. I do not know if this is an older design from the original plans. Here is a pic from station 85-137 please advice. J-Shliker
