I've wanted to have a crack at this for a while - a complete SWORD fleet but NONE of them Century 21! It works! A lot of fun too. The 2 '?'s are SCOUTS 2 and 3 - I really can't find any toys or models remotely similar. SCOUT 1 is not a direct copy of the C21 space boat I admit - but it does the job. As there is no known Moonbase toy or a copy I have simply missed it out.
There's a nice little Xmas SWORD freebie if you can name all the toys and models in this non -21 Gallery! A completely different non-21 gallery would deserve a freebie too! Have a go!
