Hello and greetings! I have here this Nikon SB-E 'speedlight' - a vintage camera flash/lamp attachment, from what I've understood. I unfortunately don't have any cameras to test it with, but, it is in what seems to be perfect condition, like it has never been used! It comes with the original soft case, which seems to also be in perfect condition, I'm not particularly familiar with camera, so I'm not exactly sure what a 'shoe' attachment is, neither am I sure of the flash's attachment - however, if you have any questions, do not hesitate to ask, I will try my best to answer.
