Okay, the kits arrived today and were waiting for me when I got home...
...And it was instant success!

That means I can now dump my crappily-painted purchase into a strong bath of paint stripper knowing that I have some nice new plastics to put on it. :happydance:
So I thought I'd share my find here with you all (and have included some pix below) in case anybody else needs them too. Click on the images for embiggification!
First up, the horribly-painted (I think the ebay description was "Pro-Painted") Hellbore transporter:

Next is the box of the model I bought. It happened to be a JB models 1/76 M113 Fire Support Vehicle, but all the JB 1/76 M113s use the same tracks/chassis sprue. I read that that Airfix use the same moulds in their kit (bought from JB Models), but I couldn't find a box to check. Airfix models are
cheap though (around £3 for an M113), but I bought this kit for about £3.50, so it's not that expensive either.

Finally, a comparison pic of all the parts. The original tracks are on the left, the new kit sprue in the centre, and the overturned Hellbore transport on the right. You can clearly see that it is a perfect match in every way.

Well, I hope all that helps other folks who need to refurbish classic old GW Epic models! Any questions, please ask and I'll do my best to answer them.
