I know where I can get the full set of the original ALCO builders blueprints to the K-28. The drawings were delivered with the OR&L #60,70,80, 90 which were rivet to rivet duplicates of the K-28's, except for the tender. I can also get you the K-18 tender drawing. Wouldn't that set be worth a donation of $50-$100 to a great nonprofit? I think its a bargain at $200. If you want those, just reply here and I'll get back to you.
