confirming that eddie's memory has served him well. It appears to be an Omega D2v. The placard on the left side of the light house should also say that.

It looks in pretty good condition. Carefully inspect the electrical wiring before plugging it in. Some of these have a fairly nasty socket situation.

You will need:
1) negative carriers - one for each format size.
2) an enlarger lens, lens cone and lens mounting disk or plate.

The size of cone depends on lens focal length. Longer focal length needs longer cone. I have specs at home but suffice to say, you will need to know what lens (determined by film format) you want to use before buying cones and mounting plates.

So what size negs are you going to print from?
