I just opened my Lionel Mil Rd S3 261 the other day, and under very close scrutiny, I noticed it has a very slight "wave" in the boiler casting, which wave is located at the second-to-the-rear vertical band around the boiler, near the top of the boiler just above the handrail, on the right side of the engine.
I assume it's a mold mark from the casting, and is very slight, hardly noticeable, really. I was wondering if anyone else has this on their engine, or is mine one-of-a-kind?
