Finding info on and old favourite Landy

With the release of Boom Racings 1/10 scale series III 109 and the custom number plates they give customers, I'd like to make my father an RC version of his favourite Landy he ever had. Problem is we only have one picture to go off of (attached).

Is there any way I can search for details of the vehicle, just armed with the specs? It was a rather rare combination (as far as I know), being a series III, 109, straight six, hard top (van) in yellow; an ex-Wimpey construction Landy.

If there is any way to find what vehicles one has previously had registered to their name or to search for number plates from specs, then please do let me know.

The only thing i can fink of is to search on google for 'land rover series 3 hard top straight six' and click the images tab, to get pictures if them or simular.
