Thanks.
Was this the Lotus Mk.15 #619 , that got a 2 litre Ferrari 4 cyl?
If not, there were 2 15's with Ferrari engines ( one in America and one in Singapore )
In which case, I did not really earn the point...
Well I have to say that I didn't know the XV in the USA was called Ferotus.
I don't know the c/n of the Stanley Leong's car in Singapore but it was a 2 litre.
The Singapore car was active in the Far East 1961-1963.
It was sold to Rodney Seow in 1963 and I believe destroyed in an accident at Kuala Lumpur in 1963.
The car was never very successful suffering overheating problems in tropical conditions.
Whatever, you identified the car as a Ferrari-engined Lotus XV and added some additional information so I think you certainly deserve to keep the point.
More research will be required to sort out the history of the Feratus and the Ferotus!
