In recent weeks I have been working on the Liberator from Blake’s7 and this has been commented on, thank you, Ed Diment, for your comment, I was away on holidays and could not make a more detailed and considered response.
but I also like to check as many sources as I can when I look at a ship design scale, like Star Trek original USS Enterprise, the Battlestar Galactica and Blakes7 Liberator and there are a number of sources available to me now that where not there before, but as with most if not all sci-fi designs they don’t always work, and we all have our views and imagined preferences, the internet allows us to share and to agree or disagree which is perfectly understandable.
Commenter Ed Diment suggests a scale of 450m and he suggests a number of sources so for a complete look I have scaled the Liberator accordingly too 4 different lengths.
The last scale length is by model maker Martin Bower who detailed the model, though he did not build it, it was designed by Roger Murray-Leach though is also credited as the designer is Ian Scoones, but from what I have read its Murray-Leach.
The scale of 1000m was given to me by another fan who said it was suggested by Martin Bower who detailed the model over 4 days, this was in a unnamed magizine, so I thought that it would be in either Starlog or Starburst sci-fi magazine late 70s early 80s when Blakes7 was still in production.
I found it and it was not 1000m long but 1000ft/304.8m long according to Martin Bower STARBURST issue 34 from 1981 found on archive.org, here are the pages in question.
Now I find this scale does not work for me at all. so like the classic USS Enterprise 947ft I am going to say, does not work for me. next is 450ft for the Liberator, and it does work far better than 304.8m but again I am going to say, it’s not for me, not wrong just not for me. I still favour a 700m to 780m length.
The London Civil Administration Ship works best at 55m long, in terms of internal and external arrangement as I explored it a few years ago, smaller scale it becomes more difficult
