Non-genuine original type as fitted to the twin carb version Coopers and "S", with CHOKE AND LOCK written on it in recessed white paint.
This Non-genuine part uses a plastic end as opposed to the Bakelite type end on the genuine original version.
MKI & MKII Minis share the same design choke cable with the word "CHOKE" or "CHOKE and LOCK" on it. See
21A1202 for single type
HS2 carb with just the word CHOKE. If yours no longer locks on or the cable end is hopelessly frayed replace it when you can.
The grommet in the body for this cable to pass through is
CAM5969 if the hole is 11/32".
