Hello , thank you for the comments!
Warren, I use Paint.net program and use layers, on for each object
(hard to explain in détails, the better is youexperiment it and tell me by PM the problem you have...)
Well it's the empennage turn.
here is the best pic I have:

the principal interest of this pic is to confirm us that it's the same system the type H abd type N; forthose one we have more information
for the type N,this 3D draw fom the "casque de cuir" website:

and for the type H this pic from the musée de l'air plane:

First of all I cut off the plastic axe to remplace it by a metalic one:

for the 4 attachments I use rest of a spitfire photoetched and cut them to give them the good form
this is the result (damned macro)

here is the final result:

the empennage is not yet fixed because I have to add the cranks.
The photetched cranks was adapted to the plastic axe. But with the new one, , I have better to rebuilt them in photoeched , making really losenge with an hole in the middle.

But gosh, no more drills! I wil have to wait the post man...
For the rudder I think the axe is where I did the red line , but I have to think more the best way to do it...
