Tractor repair centre indeed!
OK, I'll get a new bung (as much as I like hitting expensive things): are they all much of a muchness, or is there CTB approved one?
While you're here: I read something about 5mm of spacers above and below the stem being necessary with carbon steerers. I'm using a Tester top cap which incorporates a 3mm spacer, so I was going to put 3mm below the stem: death in the face or hugs all round?

Steerer bung: anything cheap that fits, Sigma Sport does one for a tenner that ridiculously mentions sleekness, low profile and etched graphics and also boasts of an alloy bolt.
But first..... hit the original with something heavy (post-cutting) because you will enjoy it, then see if you can compress it with narrow nosed pliers or similar to re-fit. Please post a video of your attempts.

The 5mm on top suggestion arises from the fact that spacers thinner than that are rare (<spam>unless you go to Tester's Tuning Shop</spam>) and conventional top caps intrude a couple of mm into the spacer or stem. Just make sure the steerer is clear through the stem, anything over 2mm is just for later adjustment. 5mm under the stem comes from a couple of bike manufacturers who have come out against slammage, without providing any convincing evidence that a spacer between the stem and upper bearing collet really does anything useful to preserve the steerer.

What's the inner diameter of the steerer? I haz 19.8mm glue-in bung left over from when I had a 1" fork

Steerer bung, choose option from: create tool yourself taking many hours making something that will squeeze in a circular motion/ take to LBS who won't know either/ take to local tractor repair centre who will hit it/ hit it yourself/ buy hideously expensive tool from Oval.
or
Cut and buy new bung.
