Hi SPCh,
I actually never owned an AVO. However, I have just seen one in a secondhand shop lost among some old furniture, clothing, paintings, etc. I was considering buying it. It is missing its battery lid, but other than that looks OK.
I was going to ask for opinions should I buy it. If I do buy it, I am tempted, then I will post the serial number and details for you. However, I do not know whether you are interested in AVOs from Australia in the first place.
Regards
Andrew
