Alfa Romeo 8C2900B coupe [chassis 412035] from late November 2007

Touring of Milan did the coachwork and this is part of the Superleggera process of a tubing structure with a lightweight aluminum skin.

A fourth tube runs across the nose (near the headlight one) to the outer lower corner as well. Note the brackets on the frame.

This is how they did it 72 years ago and how many miles upon this 8C over its lifetime via Europe, USA (racing and driving), South Africa, Canada and then the USA before the restoration.
