Bill Welch as been hard at it now trying to finish up the pilot model for the Semet-Solvay tank car project. This project has been underway for over 2 years now. I guess you can't rush genius.
Have a look at these images and you can decide.
All Bill has to do now is locate the errant set of decals I sent him way back when and the car can be completed. I bet it's with the missing platform etchings I sent him. If all goes well, this kit will be available for sale this fall at the RPM in Naperville.
