Thanks for the links, instruction and comments. After much research and showing pictures to the American Flyer Guys here, we have, (I say WE cause it was a team effort,) established what my Father-in-Laws Circus Set is and what it is valued at including condition. Thanks again to "ReadingFan, Dave, Marty, Gene, AM Flyer, Jim, Rich. The set is now up for sale on the Forum!
Couldnt do it without you wonderful RR guys!
