The lenses are not up to current standards, not even close. And they are probably dirty inside and many enlargong lenses can`t be easily cleaned due to the atmoshere they are used in . Updating to modern glass means the Auto focus may not work exactly, but you can file the cams to shape. You also need the proper cones for each lens, but I have made them for an D4. The bellows needs checking for wear and holes.
Bulbs may be an issue if it has an old color head. The original color heads have filters that fade and can`t be easily replaced, but I fixed mine with color printing filters.
If a condenser model, be sure all the condensers are there and have no scratches or chips.
I hope I discouraged you as you seem to live in a place with few resources and personel finances seem low.
