Anybody know what the correct caster angle is for series 3 please?
It is shown in a blurry sort of way on the many internet copies of the original blueprints, but I cannot make it out...
Thank you, Alex

well, to answer my own question, the angle as shown on the blueprint looks to me to be 23 degrees.
I have calculated this by dropping a .jpeg of the blueprint into a .dwg and measuring the angle using the construction lines on the original drawing.
So until I am contradicted a Lambretta has a caster/steering rake of 23 degrees.
Alex
Update: I have found a better copy of the blueprint... the stated angle is 23 degrees...
