Cromor and Athena indicate a mid range, late 1980s model. Typically, during this period Atala named their models based on the tubest and component group. In this instance it would be an Atala Cromor Athena. I have a 1989 listing for this model, with a price of $1300 US. Based on the literature I have, this was the lowest model available in the USA. There likely were lower models, but it was probably not profitable to import them.
