Sir,

Firstly, congratulations on producing a fantastic magazine. But what I am after is some help from my fellow readers.

I am a keen enthusiast of the Itala marque and have several books relating to these wonderful cars. I am always trying to improve my knowledge levels about these cars, however, and at the moment there’s a gap. I do not know of an explanation of the rotary valve system used by Itala cars called `Avalve’. Can any readers shed any light, and perhaps provide a drawing? I can be contacted by e-mail on t_dragonas@lycos.co.uk.

I am, yours etc,
Theodoros Dragonas, Aigio, Greece
