COMPARISON OF NEW SMALLER DYNAMO PROPOSED FOR BENTLEY
CHASSIS WITH EXISTING DYNAMO.

Following your request at the conference the other day we attach herewith blue print showing the relative performances of these two dynamos.
The maximum output is of course governed by temperature conditions, but for other purposes should the battery take it a smaller dynamo can give as equally high output as the big one. The difference in cutting in speed you will see is only two miles per hour.
