Need advise! Does anyone know how to remove the shell off of chassis of an Atlas "O" steam loco C.N.J. #107 0-6-0 switcher? I have removed 3 screws (2 @ the tether end and 1 between the cylanders ). I want to change the wick which is probably charred. I have heard that it's a dog trying to get the shell off because of how tightly packed everything is.
Thank-You in advance for any help.
