John Mills Racing has for sale a pair of consecutively numbered, Weber 40 DCO3 carburetors. Numbers 3777 & 3778 were reportedly removed from a Lotus 11 that the previous owner had in his estate.
The Weber DCO3 is the predecessor of the Weber DCOE.
These very rare sand-cast carburetors were used on early sports racing cars as well as limited production Italian cars such as Ferrari, Maserati and Alfa Romeo. The carburetors are being sold as shown with no velocity stacks. It appears that the needle valves along with idle mixture screws have been replaced on both carburetors. The fuel inlet banjo bolt is missing on one carburetor.
The 40DCO3 was catalogued for quite a number of interesting cars and has been seen on others enough times to know that they were used on some cars for which they were perhaps not originally intended. I believe they were no longer in production as of May 1960 and the 40DCOE replaced them in the cars that previously featured DCO3 carbs.
Identification tags are riveted to the top covers and indicate production by Weber in Bologna, Italy. The tags also show the type designation and consecutive serial numbers 3777 and 3778.
While a pair of DCO3s in comparable condition sold on “Bring a Trailer” on 02/11/21 for $5,000.00, I believe that the consecutive numbering of these two carburetors adds to their value for the purest. $5,500.00 plus 6.75% sales tax, or best offer.
