Bill – and all,
I kept thinking I could find a photo of a T&P Geep with the DB louvers on the side of the unit plated over with the hump still in place….I didn’t find one yet. (maybe I’m just making that up?? who knows?)
But, I did find an excellent explanation of “The Four Stack Phenomenon” with a photo of an EMD 567 engine with the exhaust manifolds in the original configuration and the explanation of the changes the MP and others made to the exhaust. It also explains why some units would have the 4 stacks evenly spaced and others had them in two groups of two.
I hope everyone has ‘Missouri Pacific in Color, Volume 2’ by Jim Boyd, because it’s on page 39.
Enjoy….
