Now that I'm back in a place where I can't go anywhere for a few hours, so I have to stay here; and, while the battery on this cell phone lasts, I had a chance to look in more detail.
Y'know what no one - so far - has mentioned about the cage? (It's hidden in the above paragraph ;-) )
Also, the lr 'c' pillar (I think that's what it is) looks to have been cut and poorly ... ummm, welded?
The diagonal welded to the vertical panel I'm thinking is not _that_ bad an idea, but I don't see enough to make me happy about it.
Not sure tying the main hoop to that panel, with the weld along the side of the tube is sufficient for a spreader _function_, though there might be frame rails the panel spans which give support; tough to say without seeing it in person.
The "Petty" bar looks like an afterthought at the junction near the seat shoulder. The weld looks different, with a thicker surface bead.
Is this a special, secret candidate, known for having cage design difficulties?
