There were about 400,000 cars registered in England in 1923. Of these less than 4000 would be Sevens - so that is less than 1 in 100 of cars. The OL registration listing contains 9999 cars so about 100 Sevens might be expected to be registered OL? - and about 1 in 10 would be expected to have then last number 6 - so about 10 Sevens in total to check?
