on the case back, u should be able to see the serial number and model. there should be a metallic card or paper depending on series to match. there should also be a mini cd and a booklet.
do note that most of the models have the argon gas indicator and any authentication has to be sent to germany. if it is a U1, can be check locally. pricing wise, please check with THG.
