Pickled eggs are hard-cooked eggs marinated in vinegar and pickling spices, spicy cider, or juice from pickles or pickled beets. Studies done at the American Egg Board substantiate that unopened containers of brined eggs— marinated, hard-cooked eggs—keep for several months on the shelf. After opening, keep refrigerated.

I was looking on the net for "how long pickled eggs last" and this seems the only answer, including the page where this guy got it from so I'll just add MY OWN findings and will say that if you boil a few eggs and just put them in a jar with undiluited wine vinegar like we do, they'll last AT LEAST 3 months (in the fridge). More than that I can't say as we never tried leaving them for longer but after 3 moths they are just as good as the first day so I suspect they might last much longer than that.

They are in every fish & chip shop in Scotland and never seem to sell. Those things must last for years.

Have you never heard of "balut" or the Chinese "hundred year old eggs?"

Yea they can last a long damm time, most things pickled can last quite a long while.

YES.
