Thanks for the information, Rick, Tom, John, and Jimmy.
Jimmy--please post photos, if you can, of the wand differences.
The lister has since communicated that he isn't sure that the cleaner was purchased at State--just that parts and repairs were.
Rick and Tom - (re: comment to Rick in reply #4) I need to admit my error in thinking that the Olympia One/1401s had a different length handle than the Super J/1401s as you both stated. I wonder now if I'd seen a 1401-B with a missing vertical carrying handle--which would have left the shorter horizontal carrying handle? Anyway, I apologize for my confusion and subsequent error.
While I understand that the last of the Olympia One used the new molds intended for the Silverados, it's too bad from a collector's and tech's standpoint that the model designation was not kept 1401-B.
I like how they'd done that with using the Model AE caster mount plates on the Model F (which is why so many mistakenly call the cleaner Model AF). One would think they could have done something similar with the 1401-B and 1505 interior cover plates.
I wonder if there is an Olympia One collector in our midst that has all the different versions--like Charles Lester's Model Es, Model Fs, and others? I would think such a collector would want to bid on the one that inspired the conversation today!
