I think Pasadena has it pegged.
A few years ago I finished up a 27 roadster for a guy that had a suspension that utilized torsion bars ran inside the frame, (spring type, no air bags) and it had horizontal levers with links that attached to the axle , just inside of the batwings. The ends of the torsion bar inside the frame were landed back by the cowl and the front of the torsion bar was supported by a bushed tube, welded to the (bobbed) frame horn. The levers were attached via splined drive bushings, and the end of the lever that rode on the axle were on a slot and roller arraingement.
Ron Attebury built the one I worked on and IIRC it used friction shocks.
I know he did several more that were similar, but used links at the ends of the lever, as the slot and roller setup rattled.
That doesn't look like Ron's work though.
I see brake hoses, Poncho, so don't get the noose out yet.

( I know centerline has a standing search for that "no front brake" line

ain: Uh oh... I said it)
BTW, there is no way that the torsion bar is mounted longitudally. The lever arm length that is the radius rods would require a huge torsion bar. Look at the ends, they are no more than 1 1/2" OD. That aluminum would split in a heartbeat.
