I would say yes if you are specifically looking for a "new" axle because you don't see those everyday.
But no it's not for the real world of four wheeling because just as I did when building mine you tear it all apart and change axles out for chromos, change the carrier out for an ARB or whatever locker, and change steering most likely, and install slugs. It's probably a 20 yr old surplus so good chance seals are bad and looks like the breaks will probably have to be reworked. So all in all it's not worth twice what a used one is.
A lot depends on if it's had oil in it or not also. you might take the cover off of it and nothing but rust fall out. lol
