I've always wondered why 926 and 927 existed, as they are two isolated 2009 Gemini 2 vehicles, immediately following from 49 2008 Gemini (1) vehicles in the numbering system.
One theory I had was that the numbers 926 and 927 could have been used as overflow from the 301-350 2009 batch, but then at that point the 2011 Gemini 2s didn't exist so why were 926 and 927 not just given numbers 351 and 352? The other thing is that if they were given numbers 926/927 as overflow then why are they currently at Longstone and separated from the rest of the 2009 batch, which is currently at Marine?
I also wondered the same about the 2011 Gemini 2s numbered 951-960, why are these separated numerically from the rest of the 2011 Gemini 2 batch which are numbered 351-400?
Just some idle thoughts while I'm putting off doing more studying!
