I can only tell you what I know. The carriers and other vehicles and spare parts were buried in the late 60’s early 70’s when the yard was expanded and are most certainly there unless removed since,which I doubt. Mr Ross senior, the latest I have been told, has fallen foul of Alzheimer disease so his sons have taken over the business. The last time I met with Mr Ross senior was back in early 2000 when the “Ministry” requested a return of Armoured and other Land Rovers and he seemed fine then,being just as wily as ever with costing, as in “that’s the price,take it or leave it”. At that time the new and old yards still had gems galore to be found within. For instance a Rio,a reserve non unit issued Series 1 land rover in perfect order and an AEC Dorchester. There is certainly no harm in enquiring for you never know your luck in such circumstances.
Another point of interest was his fine collection of wartime jeeps which could be viewed at his shop located in the town.If the shop even still exists I don’t know.
If I learn of anything anew I will certainly post it.
