The K5 definitely evolved over time. I've found photos with all spoked drivers, shorter tenders with 4-wheel trucks, and a few variations on trailing trucks. I'm not going to overly be concerned with an exact match on the drivers, but something close would be fun to mimic. "Close enough" drivers with proper 36" lead truck wheels will go a long way towards a convincing solution. I'll probably leave the first driver as a spoked driver to stimulate conversation with anyone who asks.
A few prototype photos:

One of my questions on this as I'm no expert on steam locomotive components, is what is the equipment on the pilot that is has the covers over the front in this image? Also, what are the components named below the sand dome? I'm sure I'll have a ton of additional questions as this is also an opportunity to learn much more about the specifics of a steam locomotive for future projects. Finally, does anyone have a link to a decent back head photo? I'd love to add the equipment there as well such as the stoker, gauges, and various controls.

In this image, the tender trucks almost look like Commonwealth express trucks. I need to research a better side view. It also dawned on me today, that "Erie Power" is in my library of books and now I finally have a use for it.
I have the Elesco feedwater heater on the way along with a few other detail parts to start this project. Also, what is the name of the Hopefully I can actually work on it as opposed to collecting parts for it like I have on a few other projects!
I would love to find a Max Gray one and be done with it, but at the same time, I do need to learn a few new modeling skills so hopefully I'll update this thread in time. A quick search shows that the HO Max Gray model is pretty common. The O scale one? Not so much so.
