Importing Properties?

Got an old J 1.5 site with com_properties component which I wanted to move over to WP I got the Plugin working by importing the mysql to the existing wp mysql
No problem there but only posts and categories from Joomla got imported.Not sure if I missed something but none of the Properties got imported which was my main aim.
Any Idea how to handle that.The Guy has got hundreds of properties with Images so to re do all those manually would be quite a mission
