Ok, here more history:
1. bought off Steve Chambers about 50 years ago - extremely rare with EE and metal buttons, hence 2000€
2. bought off Chris Algar and paid far too much, as I wanted a 31xxx, hence 2000€ ( far less than I paid )
3. Came from the US, paid too much... extremely rare, hence 2500€ ( far less than I paid )
4. Came from a British auction against all dealers and collectors, paid far too much, hence 3000€ ( far less than I paid )
5. Came from the US, had to pay duties, extremely rare, hence 3000€
