Here are a few photos of the new streamlined steamer ..it was used on the Detroit Union club layout...17/64ths ..the cast boiler sits atop a SC Mountain chassis ..
I suspect it was made by Cheriez of Detroit ..he offered a cast streamlined boiler for a MiLoco K4 in 1937 ...so still digging for more info about it .
Patterned after the CE&I streamlined Pacific
