Baldwin had quite an export business:

The Vauclain Compound locomotives were at the tip of steam locomotive technology for a while.

The numbers built could be huge, considering the short time that they were built, even though they seem rare to us. They existed mostly before cameras were even slightly numerous, so that could explain the relatively low number of photographs of them.

Superheating was its end, but the Vauclain Compound locomotives, like the early D&RGW K-27's, were neat & clean looking steam engines.

"Superheating was its end, but the Vauclain Compound locomotives, like the early D&RGW K-27's, were neat & clean looking steam engines."--Loco 112

Oh, it wasn't just the Vauclains--steam in general in that time period was neat and trim.

It was an interesting and classic period. The late David P. Morgan said of this era (and I'm paraphrasing from memory here, I don't have his comments in front of me), that it was "a time when locomotives grew both larger and simpler. Gone were the polished brass and bright paint, the ornamentation of the locomotive's youth. Complexity--outside valve motion, feedwater heaters, mechanical stokers, power reverse gears--were still in the future."

A touch of classic "eye candy" for those of us of the uncluttered clean steam persuasion:

Check out the photo of Midwest Central No. 6, from back in 1914, and look at how its appearance changed to that of today:
