This is the first edition of the Breakdown Service truck, clearly identifiable by the lack of interior or suspension and type 1 open jib.
It later gets suspension and an interior and is numbered 417S. Model 417 has an open jib but 417S can be found with either open or closed type 2 jibs.
417 and 417S have a tin cover at the back with a transfer featuring the Corgi dog on a red background and Breakdown Service text in black on a clear background.
