Sorry if this has been asked before.

I picked up a Omega D2 enlarger, with a zone vi cold head. Two cords one for the light one for the warmer. One bulb, and it has a connection for the variable controls. Here are my questions.

1. Do I need the variable controls, which I don't have.
2. I could find no makings on the light even though I pulled it apart, cam I assume which bulb I have, and can I use VC paper with below lens filters.
3 I alco have the parts to make it back to the condenser version, and preferences and why.

It has taken 30 years for me to have a wet darkroom again. Your help is appreciated.
