Thank you all so much for the replies and help.
What exactly is this lens board you are referring to? If it has a lens attached to the unit, do I still need to worry about the lens board? Do all enlargers have these? Or are they for specific units?
Each brand and/or model of enlarger will use its own style of lens board or lens mount, except for those few enlargers that just have a permanent thread.
Lens boards/mounts/permanent threads are what you attach the lenses to.
Lens boards are to enlargers and lenses like wheels are to cars and tires.
