What was an approximate cut-off/change-over for the forged upper plate on the distributor changing to the stamped steel? The J.S. says the stamped upper plate was late 1928, but how late?
Also, when was the change made from the earlier distributor housing with the squared openings for the upper plate, to the more common later rounded openings?
