Yes, it's a Morris 1500 Traveller from Argentina. For those that know their BMC (and BMC derived) B-series Farinas, the give away was the cut back rear tail-fins which, as far as I'm aware, were only otherwise used on the MG Magnette, Riley 4/68 and 4/72 and Austin Freeway saloons. The Morris 1500 Traveller is also interesting in that (except for the overriders) the front of the car is almost identical to the Freeway.
