While some items can be easily shipped, the enlarger is hard to ship in it's entirety economically (it can be done, but not necessarily economically). So as Matt said, much depends on location. Your enlarger, if working properly, will have significant value to the right person. There are, no doubt, people in NH and neighboring states that would value the enlarger, but you have to reach them and give them enough assurance that driving to look at it will pay off.
Photrio, the Large Format Forum, and Facebook darkroom groups are the best way to reach those people. If you don't feel you can do some basic testing on the enlarger, consider finding someone who will. Local camera clubs and stores (even if they cater mostly to digital) can be a source.
It would be best to assemble the enlarger to make sure it's not missing some critical component.
