Thanks. I have this "thing" for haystack tenders. I think I have one of every type the SP ever had except for one particularly ugly variant. I even have the 90SC-6, a one-of-a-kind made from an MM-2 tender.
The locomotive has the wrong sand dome. B&M had two variants, and SP got the earlier version with shorter sand dome. And while they came with Alligator crossheads and Baker gear, we can't find photos of that arrangement with haystack tender. But, as you know, I take artistic license.
I put all my Berks in one thread here last year. I think I even included the Adams C&O Berk.
