Is this G80-3000 mechanical and what switches does it have ?

It is indeed a G80-3000, it is mechanical, and it has MX Blacks.

The article number on the label: G80-3000LPMDE/01 says that it should be mechanical:

This model is not very valuable (despite what people are trying to sell them for on eBay...). The switches are not the smooth vintage type, and the keycaps are only thin laser-etched PBT. It's a quite plasticky and creaky keyboard. Most of them had been sold in Germany, so German layout is the most common.

Beware though that an unscrupulous seller could have replaced the innards with those of a G81-3000, and you wouldn't want any of those.
