What Model is this Eheim Power Filter?

[kxnji]

Anybody know what specific model this Eheim Power filter is? One of my neighbours had it lying around so I decided to take it. I’ve asked them if they know what model it is or anything about it, but they don’t. I’ve tried looking all over the internet but couldn’t find anything. The only thing I know is that it’s pretty old. Thanks!
