This has interested me - I hadn't realised that Turners were made in LHD but a bit of investigation reveals that about 250 950 models were built, and a large proportion went to the States, so it would have been worth the minor engineering to convert the cars.
I have found the source of the puzzle photo - the details were supplied to the Turner Registry by one Russ Filby. It was advertised on E-bay in 2007 as a car from 1959 which had been crashed in California in the 60s. The new owner from Arizona bought the remains 40 years ago, and began a rebuild. All that was kept was the chassis and steering wheel. Present situation and whereabouts are unknown.
Big car for a BMC A-Series engine. (No points expected)
