If you dimantle the unit the places that are worn will be obvious, they may be on the pin or socket/s, no doubt a bit of both. If just the pin is worn you only need make another to a size that suits, if the sockets are worn then perhaps you can machine them to a consistent size and make the pin to fit. Rather than make a complete new pin you may be able to turn the end down for a short length then add a sleeve with loctite, turn that to suit the socket diameter.

I have one on my Boxford. I also have the original tailstock quill. More effort is needed to drill large holes but they have a lot more feel so I have never been tempted to revert to the original.

I'd assume that the parts all came from the same source and mine does have a very slight problem. Over the years the wide end of the morse taper has spread a little meaning I had to sand the outer diameter of the quill at the end a touch. This suggests that the morse taper was very slightly off. As it's easy to cure a minor point really. It grips really well but in it's original form things might not be so good in that respect. Hard to say. The main reason morse tapers use such shallow angles is that it does offer some tolerance.
