Thanks for the offers, guys. I have 18 of them now. Found them 2nd hand on the net, and bought them one by one.
The shipping costs would be ghastly for such a little number (only 10) and I am a little bit on a budget. So I'll wait and see what comes up. I'll be going on vacation in a little while and visit many other countries. As my partner and I love visiting toyshops, I hope to find some. We' ll see.
Otherwise I'll make due with the red shielded ones. They are still available here.
It's just I have a weakness for the green shielded one. It started off my new collection. Together with Cleopatra by the way.
