Krokus 44L Color, specs and manual.

Hello

This is my first post here.

A couple of friends and I wants to build a photo lab, we are thinking about a old Krokus 44L Color.

What i need to know is: What lens 'mount' does the Krokus use ? I know the most common enlarger lens mount is 39mm, can I expekt the Krokus to use 39mm as well?
Where can I find a downloadable manual ?


Thanks
