The stitching along the cockpit edges reminds me of the cleated stitching on a WWI airplane like the SE5a and a few others. I assume there will be leather there, though? Whereabouts in Oklahoma is that (general area, no need to be specific)?
One issue, dunno if it'd be a problem, with the pictured side by side version is that having a passenger or not would make a significant CG change. In the tandem version the passenger is right on the CG so it doesn't shift.
