I usually post in the Hi-Rail forum but I figured this might get more attention here. I'm looking for parts to make a stack extension for an ATSF 3460 class Hudson: http://sfrhms.org/files/Sandifer/Stacks/Tele.htm
Precision Scale and Stevenson Preservation Lines don't have anything resembling this type of smoke stack. Is there any other source for these stack extensions already made in O scale or am I going to have to make it out of brass tube and sheet?
