English: Although the panels surrounding the engine compartment were shared with the Peugeot 302/402, the label beside this vehicle at the Peugeot Museum in Sochaux stresses that this van was a standalone model, and not a "version" of a Peugeot passenger car. This contrasts with the Peugeot 202 van which was essentially an adapted Peugeot 202 saloon.

According to the label accompanying the van in the Peugeot museum at Sochaux:

« Les utilitaires volent leur offre se développer avec des modèles de tonnages moyen, les SK, non directement dérivées des véhicules de tourisme, avec lesquels ils partagent toutefois les motorisations. Ce véhicule reprenait le moteur et les formes avant de la 302, et comme le disait la publicité d’époque: une SK3 pouvait transporter 12 sacs do blé, 6 fûts de 200 litres d’essence, ou 4 pièces de vin. En 1936 une petite série de MK reçoit un moteur diesel d’origine Peugeot.»

However, the vehicle exhibited had nothing more onerous than a spare wheel on the floor of its load area. Elsewhere in the museum it is stated that despite Peugeot’s work on diesel engines in the 1930s, the company was reluctant to share its diesel technology with the German occupiers, and only one diesel engined chassis survived the war.
