According to noted authority, Anders Clausager, approximately 59,500 cars, all built at the Morris factory at Cowley.
Production breakdown by year model:
This information is gathered from Commission Number information contained in factory BMC Microfiche for the 1100/1300 line.   Using this method to guage production numbers results in in a slightly lower number of cars produced at 58,472, compared to the "approximate" 59,500 quoated from Anders Clausager's book on the ADO-16.
1968 & 1969 . . . . . . . . 37,735

Single 1-1/2" S.U. HS4 carburetor mounted to a combination
intake/exhaust manifold. 
Early cars had a fixed needle type carburetor.  The later cars had a swinging needle type carburetor.
The air filter housing had an intake tube that was bent into a curve shape.  This could be positioned "down" and placed into a heat shroud that was mounted around the #4 exhaust manifold runner for cool or cold climate driving.  Using this position helped prevent carburetor icing which led to misfiring at cruise speeds and stalling in stop-and-go traffic.  The intake tube could be mounted in the "up" position for warm weather driving.
An "Induction Heater" was fitted in a spacer block between carburetor and intake manifold to heat the carburetor in very cold weather prior to starting.  Some models also had a carburetor piston dome heater band tied into the tempurature sencing switch on the induction heater.  (In cold weather, the owner's manual advised turning the ignition key to the "on" position and letting the carb heaters run for a minute or two prior to cranking the engine over.)
