My own travels are generally more limited, so mostly I have a 4-way 13A block with a Schuko plug from a sacrificed IEC lead (no chickens, this time) but for south Italy have another adaptor for the odd in-line sort of plug they often have.Due to my own travel and also professional rental hire I have stocks of pretty much anything to anything when it comes to adaptors but they're all made by me, not those silly tourist adaptors you get at duty free. Schuko <> 13A by the box load, Swiss, old Italian, Israeli, North American, Australian, Chinese.....
