They ARE different.

1. Rudder has different mounting points location. F/G/K rudder has 2 points
2. Rudder has different square and shape
3. Fin shapes are different also.

I don't think anyone is disputing the fact that the different design variants of the BF-109E/F/G/K experienced design changes. That is silly to dispute.

I am and I believe Graham is also speaking about deviation and distribution of manufacturing errors. Using multiple blueprints of varying measurement for the same type is beyond stupid from both a business and an engineering viewpoint.

When they hit the assembly line floor and the jigs are built, they are NOT different.

Do not confuse the wealth of pre-production and even post production information with that used on the assembly line. The Luftwaffe aircraft are probably the most prolific in their design changes without a re-designation of the type. The FW190 for example had three different aileron hinges with at least 5 different structural designs for the aileron itself. If you understand the affect of hinge point changes then you understand the significance on the stability and control of the design.

The documents you have certainly fulfilled the task and conveyed the information the author wished whether that information was precise or relative. That does not mean that had anything to do with assembly of the jigs or the actual aircraft rolling off the production line.


All the best,

Crumpp
