What REALLY needs to be offered by Lionel for their 'S' American Flyer Union Pacific "Big Boys" and "Challengers" is an auxiliary water tender in UP Armour Yellow! My son has a Big Boy and I have a Challenger that really need at least ONE! I've thought of scratch building one or two, but can't locate any scale plans. I've got dozens of photos I could possibly make them from, but it would be a LOT of WORK! Either style would be okay by me! (See attached photos.)
Any other 'buyers' out there? ;-)
Regards, Randy
