The Marlborough-Thomas 1½ Litre was a car made between 1923 and 1924 with 6 examples being produced.
The car was fitted with a four-cylinder 1493cc engine with twin-overhead camshafts. Power was transferred through a single plate clutch and a four-speed gearbox.
The chassis was 9ft long with torsion bars and hydraulic shock absorbers all round.
The chassis cost £525 when new with the customer using an outside coachbuilder to supply the body.
