I thank you all for the replies I got to my previous questions.
Therefore, here is another one concerning rudder spare parts.
I attach a technical drawing I had from the Italian representative of ALUBAT here in Milano.
What I am asking is whether someone can specify where I can find parts indicates ad "BAGUE ERTA" vwith various numbers and parts "AXE GOUVERNAIL" corresponding to parts number 1 to 10 in the drawing.
On teh drawing there is also acronym of suppliers of these parts (AMPM, SCPM) that I cannot identify and find on the web.
Merci beaucoup for your replies and info.
