Can anyone give a definitive answer as to how to tell a Fug2 from a Fug4?
Pic of Fug - apparently a Fug2 This I understand to be a Fug2 - it has a pointy up arrow at the point the top frame rails have the bend in.
BUT, the photo of a frame shown half way down this topic shows the same pointy up arrow where the fraim rails bend
Photo posted by Knightyand is supposed to be a Fug 4.
This is said to be a 2 not a 4 and again has the pointy arrow at the bend.

My Fug has the arrow at the bottom of the windscreen, not where the the top frame rails bend

which is the same as these...

BTW my log book isn't very helpfull, except that it is nice and open :D
