TRADE: Screen 1

We like to enlarge our collections in every way possible:

If you want to swap with us there are some points to consider:
* All specimen must have at least good geographical data
* Geological info is very important too
* Check first by E mail if we are in need of your material
* Postage is high, so don't send poor material: it is simply not worth the money
* Specify as precisely as possible what you want in return

We also want to buy material. Please do remember we are a foundation for the general good. We are not sponsored by anyone. We also have no admission fees. So we can't pay high prices. If you want to sell commercialy , just forget us. We would however be grateful for friendly offers.

Sometimes we have surplus material to offer. We prefer swapping !
