On the Sunset Mike: Sunset does generally spectacular work - a lot of bang for the buck. The SP Mikado, 2-10-2, and 4-10-2 came with incorrect boiler tapers, and the Mikado missed the boat on the Hodges trailing truck and tail beam.
So far, the only truly accurate SP Mikado in O Scale is the Lobaugh 1939 offering and the later lost wax version of the early '50's. That one is still available from Stevenson, albeit modified with etched parts.
From your photos, these Mountains look really good! Do they have round boiler bellies?
