It is almost certainly a typesetting keyboard, and while Boeing would likely not have been using it for a newspaper, they would have had plenty of manuals, technical documentation, whitepapers, and the like - all of which would warrant a professional in-house typesetting solution for a company of that scope. The layout reminds me a lot of Compugraphics consoles, with the arrows and other navigation on the left... yet still different than other Compugraphics keyboards that I've seen. Definitely does not resemble other early digital typesetting computers that I'm familiar with - I don't believe it to be a Wang, Toshiba, nor Linotype. And I certainly don't think it's an IBM - far as I know, they didn't have much of a middle era between the Selectrics and their far more modern, compact word processors, instead clinging to their makeshift Selectric-as-interface-to-a-PDP solution.
