LML/49/3 (UMC 66)

The third of the three works cars built in 1949 known at Works as "Le Mans Fixed Head Coupes" (LML/49/4 is a road car built for David Brown using the same lines).
A later record calls them "DB Mark II" and a log book issued in 1961, "Saloon".

LML/49/3 is the first car powered by the new 6 cylinder.
This engine, with three SU carburetors as fitted for Le Mans in 1949, developped 120 bhp but suffered from overheating. It took a long time to solve this problem hence the nickname of the car: " The Sweatbox ".

Body number 48004.
Engine: LB6/49/20/R
Registration: UMC 66.

Almond Green with green interior.

Please note that LML/49/3 lost its grille very early as it had only a chrome surround at Spa.

It is reported that Charles Brackenbury took the "Sweatbox" back to Feltham and that when the engine was opened up, the crankshaft fell out in two pieces !

Subsequently used as development vehicle for DB2.
