Austin 7 Dynamator (accuspark.co.uk)
There's history on these.
Opinions differ about the basic item but when first launched the manufacturer supplied them with new gears that wore very rapidly, sending iron grindings around the engine and causing chaos and heartbreak. A forum search will tell all.
It is essential that this modern drive gear is replaced with an original Austin item. If you're not certain please check immediately . If it is a modern one you may need to take action to clean out the engine. Others have first hand advice
