Thanks for the replies, I had forgotten there were plastic toys from the Brandstatter stable before PM! Seems the most likely explanation (if it has Geobra stamped on it, for example, then its a reasonable mistake by the seller to assume its PM!)
Chachalote- you will be my first port of call for all questions piratical! Thanks for sharing the tricycle pictures, its good to see another market for natural cork, as the production of natural corks for bottles has been threatened by synthetic alternatives and the Cork Oak forests are a fantastic natural ecosystem in your part of the world (surprisingly, the survival of the forests depends on the cork bark being harvested, if I remember correctly). Our local bicycle manufactury makes electric/pedal powered bikes- much more my style of cycling, (especially in this hilly area!)
