Kind of you Mjfnet.
I'm thoroughly reading your post and I'm trying to fully understand in Italian some terms I am not used.
I think that your solution is the neatest I have seen up to now.
Before looking at your picture I had already identified Tanner as "the" solution, now I am trying to contact them to see if they can ship overseas.
One more thing: should any doubt arise, I will come back you.
Thanks a lot for now.
