Here's another newspaper article to add fuel to the "solo" fire:
Vintage Boeing biplane takes reassembly stop in Everett - seattlepi.com
There are several photos of Ewald managing the reassembly of the Stearman at Paine field.
I particularly like the caption of Image 8:
... Gritsch has tagged along on Curtis-Taylor's flights all over the world, performing maintenance, repair, and reassembling the plane when it's shipped, as it was to Mukilteo.
