If as I suspect there is no MT, then gently file this one into some sort of shape and use it.
Or get one that fits into your chuck now you have one! e.g. https://www.yandles.co.uk/planet-mc02a-multi-chuck-drive-centre-2-prong-1-254mm/p4774 (not recommending this one particularly just put it there for the picture!)

No mate there's no MT just a solid non-hollow thread which was a bit disappointing. My chuck still hasn't arrived in the post so I thought i'd get this refurbished for the mo. And appreciate the link.

Thanks Les, she's an oldie goldie which is why I wanted to hold onto it. I was thinking that if the machine shop skimmed it back and repointed it with new dogs there's about a 1/4" inch to play with.

That's a cracker of a suggestion. Thank you for that.
