OK, so first, this isn't really scratchbuilt, I made it from my resin castings, so don't throw it there to quietly die.
Second, it's not a product announcement, I really doubt I'll convert this to a kit unless I get a LOT more interest than a think...
Third, it's not RP printed, it's resin....
And the challenge was to me, personally!
I've been tinkering with a 1917 era Cole Brothers circus train now for several years, back to my local connection. It's a struggle. Makes it easier with the MT flats, did some resin casting kits for baggage wagons and a couple others. But the elusive one is a standout, the pole wagon. Monster wagon and the heaviest one of any circus. Nothing currently made or RP printed is close to what I was looking for.
I've found a couple vintage photos, but nothing to really hang my hat on except a MAGNIFICENT O scale model that was scratchbuilt of the Cole pole wagon that matches the vintage B&W photos I've seen. I found some good dimensions of a similar wagon and adjusted it to match that model as best as I could.
So here's what I found:

http://www.randgust.com/Polewagon02.jpgThe beauty of doing this in resin instead of RP printing it is I can embed .010 wire in the molds before casting to give those delicate .020 cross sections some strength. You can't see it but it's in there.
The nuts part of this that about got me was bending and drilling those brass pole supports with #80 wire to hang them and not just break off the first time you touch it. That elevated this into the 'probably nobody else is nuts enough to try this' level.
The poles, good lord, should be way long and yes they nested a wagon between them:

He's doing a much later era Ringling and can RP print things I only dream of, I'm still in the 'if the only tool you have is a hammer (resin casting) every problem looks like a nail!)
