My search for a foundry is finished, thank God, yesterday I found a plant!
They will make me the 30 sets, in suitable material for a fair price in a reasonable time.
It will took more or less 6 weeks to held them in hand, so the complete machining maybe ready before X-mas..........
Next question is the shipping...........to find a facile solution for such a bulky parcel, because I will try to make a all-round carefree package, with the pre-assembled strutbar ready to mount.......
I'll still keep you informed. ;-)
