ARMATURE
Armature for a Lucas magneto, the rotating component that generates ignition spark.
This is the armature out of a Lucas magneto, the rotating heart of the magneto that generates the spark for ignition. The catalog places it against magneto figures covering both manual control and automatic advance-and-retard setups, so it's magneto-specific rather than a generic electrical part.

Our records show this number turning up across catalog entries from the early 1960s, tied to Bonneville-era magneto listings. If you're chasing this for a K2F-type magneto rebuild, this is the part that spins inside the magneto body to generate current for the points and coil circuit feeding your ignition.
Magneto armatures wear at the bearings and can lose magnetism over decades sitting in a shed, so if you're troubleshooting a weak or no-spark condition on an older magneto, this is one of the usual suspects. Give us a call if you want help confirming which magneto body this armature mates to before you order.
