here are a couple of delightful period shots of the prototype department,You will notice that they were not above working on more mundane Bugatti projects [ ! ] as here with a T50b motor for a Schlumph car.Notice if you will the prototype T252/3 chassis leaning haphazardly against the wall in the background ! Also l'importance of "le nourriture" With cylinder liners and weber carburettors lying around the benches it could hardly be regarded as a "clean enviroment"

Leaf springs? I see coils!

you have a preference for backsides? the leafspring is at the front ! Coilsprings at the rear.

voila coils at rear leaf springs at front and a collection of parts in the Bugatti stores.What can be identified here?
