Although it's already been said, i can 2nd the gear design problem on the Dynamator, after 50 miles it had chewed nearly 2mm off the inner edge of the cam gear.
The bevel angle on the Dynamator gear appears to be shallower than the original.
Anyone who's bought one with the gear, as Ruairidh said, swop the dynamo gear for the original one.
Accuspark MD "We acted on information supplied to us from the A7 owners club that the unit had been tested and was correct for production.
We have had no information regarding any specific problem with the unit, or cause of failure, In fact we have information that gear problems are not uncommon on this vehicle due to the large variation in tolerances with original gears. Subsequently we are not in a position to accept any liability for any consequential loss."
But does the angle of the timing gear bevel vary on different Austin 7 years and production batches?
They now sell it without the gear. Apart from that mine appears to function well.
