Below is a comparison of an original Citroen drawing with the (almost) completed model of the engine and gearbox.
The fan belt, ignition wires, fuel line, and the crankcase oil breather downspout have still to be added.
The rocker cover can be removed to reveal a fully detailed cylinder head ...
The double timing gear chain is another hidden detail ...
The"Camembert" air cleaner & Solex 30HTD carburetor are historically correct for this model.
Below is the right hand side showing the starter motor and dynamo.
The gear change levers and post are just visible behind the dynamo.
