John,
This is the one I'm working from...
http://www.rr-fallenflags.org/wm/wm-s762ahv.jpgAs you can see, the boiler diameter of the Bachmann is a bit narrow, and the overall length is a bit squat. But I actually think the wire braces are pretty close. These were structural members that replaced the support that would have otherwise been supplied by the ladder assembly that holds the pilot level above the forward truck... hence they were fairly beefy.
I'm going for overall flavor, not an exact replica. Sorta like that GP40 that Rob pinned my ears back about a month or so ago... ;D
Chris, hold onto that certificate until I have the operating Z scale bicycle finished. I'm still trying to figure out where to put the decoder...
