John Freeman kindly passed on the following information from Marcus Hearn, which I hope he won't me quoting:
We're putting the finishing touches to Volume 3 now. I don't have a press release but I've attached the contents page and the jacket so that should give you what you need. It's restored to the same standard as the first two volumes and approx half the pages are scanned from original artwork.cheers,
The latest volume contains the following stories drawn by Bellamy:
ATOMIC RUNAWAY #192-196
ATOLL OF DOOM #197-202
THE MANAFU TRENCH #239-242
The first was reprinted once in the 1990s Thunderbirds comic (numbers 25-27 for those completists) as "Nuclear threat" and if you are Dutch in TV2000 # 1 - 3, 1969
The second was also reprinted once in the same Thunderbirds comic (#25-26) as "Hawaiian lobster menace"
And lastly Thunderbirds #42-45 had the only reprinting of the story titled "Danger in the deep".
I, for one, will be really pleased to see these stories again - especially if they contain a lot of the original artwork. The first two volumes (mentioned here) are absolutely gorgeous. Paul Holder and I spent an evening looking at each page and deciding how 1) the original artwork did not get reproduced so well in photogravure (surely the best there was at that time) and 2) deciding which pages were from the originals and which weren't. The reproduction in the first 2 volumes is so crystal clear that I couldn't believe how muddied some of the original TV21s were!
