Re: Deep Thinking----Here comes trouble......

Thanks Earl and Hank for your input, and I Understand about the dimensional differences of a K27 vs. K37 smoke box barrel and the length too could be off too. I am just thinking that when the K36's proved their weight in gold, that the need for smaller power upgrades declined and/or the need to complete the all the K27's, that the Rio Grande were going to preserve to superheated spp's got scrapped, and possibly the, on paper only, allotment of superheaters and headers went toward the K37's instead of the K27's. Sure wish there were more documentation of these proceedings, in the history books.

Still a Student,

Dave
