This is a 1950 Lea Francis 2.5litre sports. It has a 4-cylinder 2500 motor and it weighs in at about 850 kilos. So, it is a fair sized motor for a little car. It is reputed to have a top speed of 100 MPH ( I haven't tested the claim). There were about 77 built of which 11 came to Australia. There are thought to be about 40 still in existence.
