Let's sum up:
#10: Not a Wiima, but from the same country...(and I found this pic online in a page where you can find the Wiima too...)
#11: 1st shown in Zagreb, former Yugolslavia. The car was shown with a name still in business and I have another pic (that I'll upload shortly) with a sign where is the builder's name too.
#12: Italian, Puch-engined
#18: Italian, 1-cylinder, 0.8hp at 4000rpm...that man is a very popular American singer.
