You’re welcome. Hopefully you can catch a ride on it. That would be cool.
A few years back I stopped in Cheyenne, WY and took some walk-around photographs of Big Boy 4004 that is on static display there. They were in a photo-feature on the old site. I will have to see about posting them here on the new site.
Perhaps you can contact Jimb. I went out to a hobby shop a few weeks ago and obtained a replacement. Pyle generator in brass that he needed for his Revell Big Boy. Maybe you’ve got a photo or two that could show him how it was plumbed.
