It's worth the wait.
Trawling pictures of the 3ro to see if the Gordini race transporter might be a reused WW2 autofficina (as you do, and it probably isn't) I came across Geoff Goldberg's Lanciainfo blog and clicked on Museo Nicolis which contains this You Tube video. Bear with all the waste paper, it pays for what comes next. That exhaust note would give the Beast of Turin a run for its' money.
