Hi Speddy,
Some explanation:
For reference please take a look at the data sheet of the LG 1750, page 15 (transportation plan). There you can see the designation of the system as well as the outer dimensions.
Comparing the outer dimensions with the system designation we've got:
2826 - 3mx3m
2421 - 2.6x2.4m
Thinking about this my conclusion is that the system designation refers (as i wrote in my last post) to the distances of the centres of the four corner tubes of the mast segments - or, if you like, to the distances between the centres of the bolt connections.
So I assume that a mast section system 2826 has a dimension of 2.8 by 2.6 m from centre to centre of the corner tubes. Given the outer dimensions of the section I would assume that the corner tubes have an outer diameter of 193.7 or 219.1 mm (which are standard dimensions of steel tubes). So you get a total width of 2,800 mm + 193.7/219.1 mm = 2,993.7/3,019.1 mm, what gives 3 m if rounded.
Of course - these dimensions are no facts, but just the thoughts I have when I think about the designations and what system would stand behind them.
So again: all this is just an assumption. I may be right, I may be wrong. It's just what I think and how I would do it if building a model. If I am right, the 2.8 m might be 2750 or 2840 mm too - but I think such differences can be neglected.
May be I'll get the possibility to take measure on a mast section sometime in the future. Then I would know If I'm right or wrong. 
btw: DEMAG uses similar designations for their mast sections.
cu,
robert
